Right,
It was covered some time ago (coupla years maybe ???) in the
sailing conference, I'm surprised you don't remember it.

| Hi Lou.
You can tell if your cutlass is worn by sighting down the shaft. There
should be no differance between the angle of any of the blades from one
another ;when looked at from ether end. Having done this, proceed to
try to wiggle your shaft by hand. you should not be able to move it.
There is no diffinent time interval that I know of for replacement.
Just replace when worn. If you get monofiliment fishing line wrapped
around the shaft & bearing it will cut right thru it. check for any
visual damage ie: cracks, broken blades, ect....
Do you have a wobble? Is that why your asking?

| re .0:
My cutlass bearing was still in good condition after some 900 hours of use
(propeller shaft speed less than 1000 rpm). But I suspect that a little
misalignment or higher shaft speeds would result in (maybe much) shorter life.
Replacement requires, at a minimum, removing the propeller. Removing the
propeller shaft also makes the job much easier. Look at a picture of a
propeller removal tool in a catalog. It is easy to make a similar tool that,
with a piece of pipe a little smaller than the outside diameter of the cutlass
bearing, can be used to press the old bearing out of the strut.

with the engines, while your up on the beach, or goodbye.
Noticed one of the replies mentioned shaft removal. Fine
but the tool used is a torch.

| Oh yea! speaking of prop removal. The dealer must have used an inpact
hammer to put the prop on my new boat last year. I tried to get it off
after 4 mo running and I had to use a 9 ton puller and set up a
resonance vibration to budge it. Of course I forgot to leave a loose
shaft nut on to prevent the prop from flying off when it popped.
You should see how far a 18 x 16 three blade nibril will fly, it must
have gone 10 feet after deflecting off the rudder. Luckly I was not in
its flight path. I won't do that again
As far as a new cutlass goes, try giving H & H props a call down in
Salem Ma. I know they carry them. They may even know a few easy tricks
to change them.

>>> Noticed one of the replies mentioned shaft removal. Fine

I assume you're referring to removing the shaft from the transmission
coupling. It can be done without a torch. I got some long bolts, put a piece
of bar stock (actually a deep socket wrench) between the transmission flange
and the propeller shaft, and used the long bolts to pull the transmission
coupling and the transmission flange together. This pushed the propeller shaft
out of the transmission coupling quite nicely. Of course, I have only a 1"
diameter shaft and the process might be more difficult with a larger shaft.

526.7 | A wobble (?maybe?) | SALEM::KLOTZ | | Tue Oct 03 1989 10:15 | 26 |
| The reason I'm asking ---
I had a bit too much drip in my one stuffing boxes this past weekend
so I snugged it up a bit --
Then after running for a while (& while crusing at a slow speed)
I gave Patty the helm & went below to be sure it wasn't too
snug (i.e. heating up)
It appeared that the shaft had a wobble to it -- I'm not sure
if this was an optical illusion due to the stuffing box needing
new packing & vibrating itself - or was it really the shaft(?)
I suspect its the box; however, I did have some mono fish line
on that shaft this year -- ergo some concern.
The engines have about 375 hrs on them.
I have to admit all this talk about pullers, tourches, etc..
is a bit discerning - being naive & looking at the assembly
it appeared that removing the shaft would be a snap.
Oh well we'll see when it's pulled for the season --
Living & learning -- ain't boats wonderful,
Lou

526.8 | check it now... | TYCOBB::J_BORZUMATO | | Tue Oct 03 1989 14:33 | 11 |
| Lou, if you got a wobble, you got some vibration to go with it
at r.p.m. (2800+)? If so have the marina at least check out your
alignment before you pull it. IT CANNOT BE DONE ON THE BEACH.
Sorry for hollering, but this would be about the best time
for an alignment to be done. It cannot be done in the spring
until the boat has settled. Usualy takes about 2-3 weeks.
I think the spec say's .005 is acceptable at the plates.
You can check this yourself.
Jim.

526.9 | No Noticable Vibrations | SALEM::KLOTZ | | Wed Oct 04 1989 15:24 | 33 |
| I'll have to check again this weekend; but, strange as it seems
I have not noticed any real vibration at any RPM ---
The only reason I noticed this at all is because I went down to
check the Stuffing Box - & I believe I see a wobble.
I'm trying to think of some way to tell if it really is the shaft
or is it the stuff box (because I know it needs repacking), or just
an illusion due to some oxidation marks on the shaft.
We'll see Sat.
Lou
p.s. All this feedback is appreciated & interesting.
I called H & H Props in Salem and they said I should expect
3-5 years out of a bearing -- suggest if it needs repair that
I remove the "entire strut" from the boat & bring it in so
they can fit the bearing in place.
Called another place & they said I should get 8 or so years
out of a bearing & suggested I bring the Prop/shaft in to check
them out first.
All solutions seem simple enough:
DIS-ASSEMBLE BOAT - REPLACE WORN PART - RE-ASSEMBLE BOAT
Huh?
Lou

526.10 | | MSCSSE::BERENS | Alan Berens | Wed Oct 04 1989 17:05 | 15 |
| re .9:
Remove the entire strut??? They've gotta be kidding!!!
Offhand I don't know the exact tolerances, but the shaft diameter should be
within a very few thousandths of an inch of its nominal diameter. If the shaft
has been worn very much by either the cutlass bearing or the stuffing box, it
may need to be replaced (ugh). Wear can be easily measured with a micrometer.
re stuffing boxes:
Throw the thing in the nearest EPA-approved trash bin and buy a Lasdrop. Mine
(which is the older, not quite as good as the new design) hasn't leaked in
five years and has required no maintenance. In the Lasdrop all the wear is
between pieces of the Lasdrop and not on the propeller shaft.

526.11 | STILL NOT SURE | SALEM::KLOTZ | | Mon Oct 16 1989 11:15 | 36 |
| Well -
The boat is out of the water (Sigh.....)
There is a small nick in the prop; but, it doesn't look like
enough to cause any wobble, etc...
I STILL CAN'T TELL If there is any problem with the Cutlass!!!
About 30% of the "Marina Experts" seem to think I should replace
them while the other 70% says "...nah, you'll get another 3-5
years.."
For some reason I don't trust myself on this one - I don't want
to change anything that ani't broke - yet I don't want to relaunch
& then find out in August that there is a real problem.
When I try to move the shaft - it feels very tight to me; but,
how does one "feel" about .005" play?
The Back of the one cutlass shows a little wear - I think from
a peice of mono - it's about 1/16" shorter than the other -
inside the strut - But considering the whole bearing is about
4" long it doesn't seem it would matter much.
If I rotate the prop by hand back & forth I feel a very slight
"clang" -- some of the "marina experts" say this is the bad
bearing; but, I then to think it's a normal "clang" from the
transmission gear box and I'm just feeling it at the cutlass
cause that's where I'm at...
Any last thoughts still appreciated --
At this time I'm tempted to leave well enough alone under the
pretense that I might be looking too close.
Ah - if I only knew what I was doing,

Its probably safe to say that clearances of less than 0.001
can be felt by most people on most assemblies.

Dunno if you work on cars Lou, but if this feels like what
happens if you try to turn a rear wheel (rear drive car, in park with
parking brake off, but with the wheels chocked) with a car on the jack
then its just the gear lash, nothing to worry about. On the other
hand, if you can feel side to side slop (non rotational) then its
likely the bearing - as to how much is too much,,,,,,,,, as I said, it
could be less than 1/1,000 inch and still detectable.

526.13 | the answer...... | TYCOBB::J_BORZUMATO | | Mon Oct 16 1989 16:21 | 25 |
| Lou, to me its sounds that you are looking to close. I don't think
you have a problem. However, i'll answer "how do you replace them"
them part.
1. Pull the shaft.
2. Using a hacksaw, remove the blade, put it thru the cutlass,
reconnect the blade to the handle upside down (teeth facing the
handle) saw thru the rubber bearing and down thru the bronze
sleeve. DO NOT SAW THRU THE STRUT.
3. Using a 3/4" threaded rod, 2 nuts and 2 large washers,
put hardware on one end, slide on new cutlass, slide
this thru the strut, put hardware on the other end,
hand tighten both nuts, line it up, using 2 wrenches,
tighten until cutlass is seated.
4. Re-install shaft,prop etc.
5. Drink beer.

| There's an ABYC standard for shaft-to-cutlass fit. If you get into
replacing the bearing, you must mike the shaft and the bearing to get
the correct initial clearance.
My latest whale has a 25 x 25 prop on a 1-1/2" shaft, and the cutlass
needs replacement. So far, I have: removed the rudder, disconnected
the shaft coupling, pulled the shaft and prop out of the shaft log,
paid $108 in machine shop time to get the prop off the shaft, and spent
some time disconsolately staring at cracked rubber in the bearing.
Some of the hints above sound helpful for removal, but I'm goiing to
wait until I have at least sandblasted and primed too many square feet
of steel hull inside and out.
Lou- I don't think you have a problem. I do think that some of the
replies above seem to have confused cutlass bearings with stuffing
boxes and runout with clearance. With the rubber bearing, you'll
know when it's worn, it'll rattle and make noise and carry on and
you'll still get home OK, maybe slower than you want.

To replace or not to replace, that is the question.
Whether tis wiser to replace the strut bearing (cutlass)
while prop and rudder are at H&H or reassemble the boat and
check for vibration first...
I can feel a little movement in the shaft around the area
of the strut, but how much is too much? How can fishing line
(opps sorry about that you guys) damage the bearing considering
it's almost completely enclosed?

Note 776.0 Props & Cutlass Bearings No replies
SSVAX::REDFIELD 27 lines 18-DEC-1990 08:41
--------------------------------------------------------------------------------
I just received a Christmas greeting from the boat yard where my toy is
stored for its winter nap.
The greeting stated that my propellers are dinged and one blade is bent.
Additionally my port cutlass bearing is worn out and needs replacement.
Their recommendation is to have both props reconditioned.
Quoted costs are:
Remove & re-install 2 props $ 75-100
Recondition and dynamic balance
2 props - Nibral 225-300
Remove and replace cutlass bearing
incl bronze brg 225-290
They suggested that the bearing replacement need was caused my the fact
that I operate in a somewhat shallow area and that perhaps I follow other
boats to closely, thereby preventing waterborne sand from settling out
prior to going through it.
My question...Does the work need to be done (the props didn't look all that
bad to me)?... If so, do these prices seem reasonable?
thx

Of course there's no way for anyone to comment on that without actually

They seem a bit steep to me! You're talking about a potential for almost
$700 worth of work. Heck, I'll remove and replace your props for less than
$75-100. How big are the props? That price also sounds expensive, especially
if they don't look bad, as you say.
Why not remove them yourself and have them reconditioned at H&H? Then
the only work you'd end up paying the yard for is the cutlass bearing,
if that really needs to be done.

This seems unreasonable (to me, I'm a DIY'er - your situation
may be different, you may not have the tools, you may find doing this
yourself to be less "recreational" than I do... , etc) anyway, it
shouldn't take more than 1/2 hour to get them off and even less to put
them back. I'd bet they don't hold to the $100 if either one of them
is badly frozen on and they have to use heat (/torch).
> Recondition and dynamic balance
> 2 props - Nibral 225-300
According to diameter this may be reasonable, I really don't
know. Ski props are $60-70 for the 12 to 13 inch diameter, including
the few bux extra for cupped props. Can't answer this without knowing
the size, but I'd guess they're adding a decent mark-up to the price
you'd pay if you sent them out yourself to somewhere like H & H.
> Remove and replace cutlass bearing
> incl bronze brg 225-290
I have no data - this would probably require more (different)
tools than you'd be likely to have for normal car/truck maintenance.
If I were contemplating this I'd research the tool need first - then
the parts cost - then procrastinate til about March - then just do it
because the yard would be too busy by then (-:, (-: I'd justify the
cost of the tools against having to do the other side "next year, some
time, ....", etc. I think you only need a slide hammer and some way
of connecting it to your shaft. Getting the bearing out of the strut?
Gee, I dunno, probably drift it out with a big socket or make up a
puller/pusher with some threaded rod and iron ("gas") pipe. This
should work for shafts up to about 1 1/2 inches - beyond that....
It depends what's at hand, for example I could just start dismantling
the wine press and use the screw out of that.

....perhaps; only you have the data to support their guess.
There's all kind of other good reasons for not following too closely,
especially in shallow water<safety preaching rathole alert, what if
the other guy runs aground ?, etc> do you get a lot of sand and silt
in the raw water pick-up strainer ? Is your raw water pump showing
signs of having pumped a lot of abrasive stuff ? It might be worth
looking for some more clues like this.
> My question...Does the work need to be done (the props didn't look all that
> bad to me)?... If so, do these prices seem reasonable?
Its a personal decision - how really bad is really bad ? If
this is a performance boat the slightest dings in the props or any
slop in a cutlass bearing will matter a lot, if you rarely exceed
trolling speed its a very different situation and you might be able to
defer the expense. If you're willing to do the work yourself (and
regard the work as part of the hobby vs being a drag) you could
probably save ~$(above)/2, even if you have to put a few dollars into
tools. YIKES ! too many "If's" (-:, (-:

with the proper tools (rent a prop puller, don't use a hammer)

I did look. In fact they looked fine to me. Then I got this letter the

slightly bent at a tip (perhaps a crease of 2" @ 45 deg), the other has
some dings or nicks.

I would love to find a cheaper way out, perhaps ask you or someone else to
help with the repair and replacement. I could then sponsor a fishing party
for all the helpers one weekend in season and we could have a blast on me.
I would be learning something useful at the same time.
My boat is a 28' Bertram FBCII, and is moored in Cotuit Bay (Cape Cod) in
season. Currently in external storage (props are accessible) at Oyster
Harbors in Osterville (a $50/hr kind of place!).
Re: 526.19
>> Well, of course they are - but how badly ?
>> Looks like they're doing a little gift shopping ?
I hope not, they are reputable albeit expensive. For a bunch of personal
reasons I had to get the boat out quickly and they fit the billl for me. I
amy need to develop alternative in future seasons. This was my second
season with the boat and my first to pay for winter work as it was covered
in the original purchase agreement.

Not sure of size. I can check this weekend if it the size cannot be
deduced from knowing that it was the standard for a Bertram 28 with twin
260's (1986).

Don't believe so. I am pretty careful about operation. Will look more
often next season. By the way I am not sure what a cutlass brg does?
RE: Note 526.22
>> Just one question for the originator.....
>> YOU NEVER RAN THE BOAT IN GEAR WHILE IT WAS ON THE BEACH...
>> DID YOU???????????????????????????????????????????
If you saw my boat you would know that if it was ever on the beach that I
would know it. Therefore I can confidently state that it was never beached
by me. The closest to going aground was last August in Cuttyhunk. I got a
little to far North in the inner harbor while anchoring and dug into the
mud a bit. Did not feel any hard contact!
As I mentioned above...I am open to help if anyone feels like spending time
down the Cape. I have a house in Cotuit so comfort is available. This
task can justify tool purchase should I ever have to do this work on my own
(I have spent a lot using this justification and never using the item
twice, but the rationale is always fun). An additional benefit would be my
meeting some more experience mariners, and a fishing expedition might be
planned for the spring (stripers, blues etc.),

bearing. Water is the lubricant.
As for the props, i'd have them done.. Ask the marina "why"
they feel you need new cutlass bearings. Can they move the shaft
side to side.
The prop size and pitch is stamped on the hub of the prop.

| Re: .10
Alan, what is a "Lasdrop"? Is that some new invention that replaces
the stuffing box? I've never seen such a thing advertised in any of
the catalogues I have received. The reason I ask is because after
completely reading this note from beginning to end, I realized that
maybe I should have done more than just replace the prop shaft on
my boat. When I took the prop and shaft to H + H for reconditioning
they said that the shaft was too worn down where it rode within the
bearing (or was it stuffing box?). This note has me thinking that
there probably was a reason for the shaft to be so worn and maybe I
should have replaced the cutlass (I spelled it correctly this time)
bearing and the stuffing box packing while I had the thing apart.
My stuffing box does leak some. I'ld just as soon replace it with
a newer "gismo" if I could find out what a "Lasdrop" is and where
to buy one. It seems to me that the design of the stuffing box has
probably been around since the inboard was invented and sooner or later
someone would come up with a more "high tech" design.
Thanks, Wayne

| re .32: Yes, Lasdrop replaces the traditional stuffing box. West Marine
(among others) carries them. Lasdrop also advertises in various boating
magazines. The 1" size is $120, 1.5" $150 (or so).

526.34 | Please describe | EXPRES::GILMAN | | Thu Dec 20 1990 15:48 | 1 |
| Can you describe the Lasdrop stuffing box? How is it designed etc?

526.35 | Approximate description of lasdrop | BTOVT::JPETERS | John Peters, DTN 266-4391 | Thu Dec 20 1990 16:12 | 12 |
| LasDrop- an aluminum collar fits on the shaft, and a reinforced rubber
hose replaces the stuffing box. to the end of the hose is
clamped another collar, and an o-ring fits between the two collars.
For boats that go faster than (?) 10? knots, a provision is made to
circulate water through the hose to keep things wet and the o-ring
lubricated.
Description above is from memory at least six months old, probably a
year...

| Probably,Alan will give you a better description than the description
of the Lasdrop in the catalogs.However I have the 1990 Boat/U.S in
the office and I can send a copy of the Lastdrop picture and
description if you like.You can mail me, or call me at 237-2208
By the way I installed one last year and it is great,although you have
to be in the boat when it is lunched because it may need some
adjustmens tightening the screws.

I guess I didn't understand the original question. No I have never run the
boat out of the water. Unless...you count a couple of occassions when I
was bounced high enough out of the water to hear a free high rev spin of
the props. And that ws scary in a 13k pound boat!

Your shop is definitely not jerking you around on the fact that the props
need to be reconditioned. A 2" section of prop bent over at 45 degrees
can seriously hurt performance and mileage, and throw the prop out of
balance. In fact, if this prop is on the same side as the worn cutlass
bearing it could easily be the cause of that problem.

Are you sure you want us to help!? Last time a crew of us *helped* Walt
Gibson, he ended up having to rebuild the engine! 8^) (Actually, we
were chasing an elusive backfiring problem which turned out to be a cracked
piston). The Cape is a bit of a hike, but who knows, maybe we could put a
crew together when the dust settles from the holidays.
>> I'd love to learn, but don't know how!
Ah, that's the fun part! As long as you've got some basic mechanical
aptitude, a service manual, the right tools and a little patience you'd
be surprised at what you can do. If you're lacking the aptitude, well,
you're SOL and the other items won't help you much. For some generic
DIY boat & yacht repair books stop by BOAT/US, they've got several on the
subject. R&Ring the props is probably one of the easier jobs you can do,
with the right tools of course. As far as the cutlass bearing, I've
never owned an inboard so have never done the job myself.
>> By the way I am not sure what a cutlass brg does?
It supports the prop shaft and act as a bearing where it passes through
the support strut.

See 526.13 for an excellent description of Cutlass bearing
replacement. It worked for me... (thanks Jim)
