Like I said the pulleys don't look to be out of alignment, I will check with
straight edge, probably in winter storage. Belts on pulleys don't look to be
bottoming out all belts align up with pulleys I looked at that. Guess I
could look harder but pulleys don't appear to be worn. I also replaced the
power steering/waterpump belt when I first got the boat 2 yrs. ago, and it
is still working no problems with it. But this harmonic balancer u are
talking about K Smith, how can I check it? The part I think your talking
about is # 38 the damper crankshaft, is it
not(http://216.37.204.206/Actionsports/O...pe=13&A=48&B=4) .
Seems like the alt. belt has to be tighter than normal (but not so tight I
can't get a 1/4 inch deflection) if its very loose it will squeal, That
Damper is allot of money would like to know how to test it before I spend
$100, I didn't know it was there am used to automotive pulley on crankshaft
don't have one. Thanks for all your reply's I guess I will have to do some
investigation further, it stinks to have to change your belt on a day off
trying to go out to sea. Happy Boating

Hi does anyone have problems with alternator belts breaking 2 or 3 times
a
yr. about 100 hrs./yr. Looks to me the cause is rust on the pulleys
grinding
down the belts and leaving a nasty rubber powder behind, I always keep a
spare on board never had to change out of port,(almost the last time out
but
I thought my partner lost the anchor and I was close to port.) never had
to
get towed yet thanks goodness. The pulleys look to be running true. I
think
it is when I start it the first time for the day I have to pump the carb.
alittle, (throttle) and leave it open some and the jump in rpm's and
first
rust of the day pops it off. What do u think? Thank u all, Need Help in
Jersey.


This is (very) excessive. Check alignment, fit for sheave to sheave
and belt to sheave(s), and proper tension. Use the manufacturer's
specs for setting all of the above. Beyond this might be an overload
caused by too great a pre load on alternator bearings or more esoteric
crap..... check the simple things first..... and report back....
