1103.0. "propeller "out of round"" by MIZZEN::DEMERS () Wed Aug 18 1993 17:41

While doing a routine visual, I notice that the propeller was not spinning 
"evenly."  What I mean is that it appeared that the shaft was bent.  I checked 
it and then put on another prop.  All appears well.  It seems that the
inner part of the prop is not aligned with the outer shell.  This prop
(OMC, Al) has an inner cavity with the "clutch" innards to prevent torque
damage.  This inner shell is connected to an outer shell with "spokes".  The
outshell of course holds the blades.  When I line up the outer shell with 
a reference point, I can see it rise and fall as I rotate the prop.

So, is there any way to make the prop "round" again?  

I don't see any problems with the blades.  I'm not sure, but I may have 
detected a slight vibration.

I wanted to get some feedback before I call B&B, etc.


tnx,

    Chris, boat places around New England would send your prop to H + H
    propeller in Salem, Ma., so save yourself a few bucks by dealing with
    them direct.  Their number is listed in note 46.1.  They can probably
    tell you over the phone if your prop is worth fixing.  You can UPS it
    to them if you don't want to take a ride down there.  I've had alot
    of work done by them and their work is top rate.  I wouldn't be too
    surprised if they tell you that you should just buy another prop.

    Based on my experience, the break even point on prop repair vs.
    replacement is at around $ 75.00  That is, if the prop costs less
    than & 75.00 to replace its probably cheaper to buy a new one rather
    than have it repaired by a prop shop.

    I have dealt with H&H a lot and as stated previously, they do 1st class
    work (can't tell repaired prop from new one).
    
    However, they are not cheap.  The charge for an Aluminum prop is $60
    which is a pretty good percentage of the cost of a new one (a 14" OMC
    Aluminum prop costs $99 new).   They charge even more for SST or
    bronze/nibral props (I'm guessing $100+) but in those cases they are
    a much smaller percentage of the replacement cost, so it's a better
    proposition.
1103.4what's in a letter?MIZZEN::DEMERSThu Aug 19 1993 14:157
yea, H&H, I've used them before (probably this prop!) and they do a good job.

I just wish I didn't have to sent it there, etc.  Maybe a phone conversation
would suffice.


thx
