1073.1 | Get a new pump | 18947::TURBAYNE | | Tue Jul 13 1993 11:59 | 9 |
| Bottom line......the water pump is shot. When they start to leak out of
the hole near the bearing it means that the seal is going.....The
bearing will start to deteriorate quicker because water is inside
rusting it out....Boats and cars are no different in terms of water
pumps leaking.....I just did my 88 T-Bird. Same problem as you
mentioned; water coming out the hole on the underside of the pump and
I've done a bunch in the past......

1073.2 | Fast Idel Problem | UNYEM::RECUPAROR | | Tue Jul 13 1993 13:11 | 11 |
| Although I am not having a problem with noise, I am having a problem
with my engine in my Four Winns with a OMC ostern drive. I am having a
problem with the engine fast ideling after I've run it for a bit. I
put in in nutrall and rev the engine but it will not come down. I have
to turn the engine off and turn it back on to get the idel down. I was
told that the cable is streched out, so I have tightened it at the the
engine (turn little plastic ring) and this helped for a while. The
engine is a Ford 351 (5.8). Has anybody had this problem and does
anybody know how to fix it.
Thanks Rick

| first re: my base note...
talked to OMC Tech Support - yup, the WP is shot, but luckily, I'm still
under warranty.
Also talked about the noise. Both FW and OMC indicated that my stern swim
platform helps hold in the noise (it forms a small "band shell"). Seems
logical. Also, OMC does vent the bellows for higher displacement engines.
OMC volunteered to talk directly with the service dealer to discuss
alternatives to quiet it down. They may replace the bellows with one that
has no vents. I was impressed that OMC volunteered both a solution and a
willingness to work directly with the dealer.
re: idle
I too have problems with the idle getting back to "normal". Sometimes a
wiggle helps. Funny you should mention it, I'm in the process of doing a
tuneup, etc. and I'm working on the low speed idle and mixture tonight.
The service book is very specific about how to hook up the cable. If you
don't have the book, I can paraphrase. My -assumption- is that your
connections are similar - the steps below are for my OMC stern drive -
Model 302BMRPWS - I don't know if it works for yours...
o move control handle to first detent
o move handle back HALFWAY to the neutral position - the book indicates
that this is essential to proper throttle adjustment - failure to do
this may result in what it terms "hard shifting" when coming out of
neutral.
o attach end of cable to carb, making sure the throttle is closed (you
may want to hold it down)
o grasp thumb screw firmly and pull cable to take out slack (see note
below)
o move screw to align with clamp
o tighten clamp
from the book: "Unless backlash is removed before adjusting throttle cable,
engine may not return to a consistent idle speed"
relative to a previous note on FW/OMC/Volvo merger/sale/etc. - seems I have
the "best" of both worlds - a Four Winns with an OMC outdrive - it should
be interesting.

1073.4 | Maybe a flapper valve tearing out ?? | ASDS::BURGESS | Waiting for ZEUS to come | Tue Jul 13 1993 15:05 | 14 |

> -< status... >-
If the exhaust is noisier than others of its type, or if it is
noisier than it used to be, the exhaust flapper might have torn loose.
This is a small rubber flap valve in the exhaust riser, basically its
there to help stop a following wave from coming up your exhaust if you
stop quickly and cut the engine - - say from about 15 or 20 MPH.
BTW, you didn't say which motor you have, I know where the flapper
valve is on the 4 cylinder, but would have to guess for it on the 6 or
8.

1073.5 | gotta live with it... | WRKSYS::DEMERS | | Wed Apr 06 1994 09:43 | 4 |
| FYI - I installed a "ventless" bellows and the noise is still there.
Seems the "bandshell" effect is too strong.

1073.6 | update... | WRKSYS::DEMERS | | Mon Aug 01 1994 11:24 | 16 |
| My brother and I stuck our heads over the stern to listen and view the
outdrive at initial acceleration and full throttle. The noise
is coming from the exhaust relief located at the bottom of the
outdrive (near the zinc anode). My understanding from OMC is
that this is used only at idle because of the water back
pressure in the rest of the drive. Once the boat is moving,
the exhaust is sucked out the back of the drive. On mine, it
seems that most of the exhaust is coming from the transom.
We listened for two days to various boats with lots of
different transom designs - the FW explanation of the
"bandshell" doesn't fly with me anymore.
re: the flapper - pls say more - how would a bad/broken flapper
contribute to increased noise?
