P.S. it is a 1993, 351, OMC King Cobra.

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.

How's the tension. Properly adjusted?

It is the pulley's. My 351 was also going through belts. The 351 is a
marine engine from Ford and Red Line Marine in Lewiston, ID is a parts
distributor. The pulleys are only one the marine engine. Red Line ships,
the pulleys are not cheap. Pull the pulley's and check the numbers on them.
They are stamped in to the metal.

All the above, but also be aware the harmonic balancer (crankshaft
pulley) can move out of alignment on it's rubber bush as they get older.

Particularly so if you accelerate the engine hard with no load, as you
describe.

Also just confirm all the pulleys are the same profile (usually "A").

Marine belts on "normal" pulleys seem to last OK if properly aligned &
tensioned, so the slight surface rust you describe is not unique to your
boat.

This is an example of liar Harry's MO, he pretends he has actual
experience than he can say whatever, he invents his jetski so he can
spread his lies & hate in the jetski NGs, till they told him to sod off.

As far as your other complaints, well, almost every president in my memory,
and I *remember* Truman, Eisenhower (who cheated on his wife), Kennedy,
Johnson, Nixon, Ford, Carter, Reagan and Bush, lied and participated in
deceit to one degree or another, and on issues far more important than who
was giving them blow jobs.

Good lord. I met *every* president in the damned group except Bush, and I
worked once for his father.

So tell us, Karen of Oz, did you go to school to learn how to be an
idiot, or did it come naturally to you?

Tell us, Bill, how are you 100% sure it's the pulleys, and all of
them? Could it not be just ONE pulley with a burr on it, or worn so
that it's not true anymore? Could it not be that one or more pulleys
are out of alignment with the others? Could it be that the harmonic
balancer is not aligned properly, thus allowing the crankshaft pulley
to run eccentric?

Because I had the same exact problem last year. Checked all the wrecking
yards for pulleys. Called the marineizer for the engine, and they sent me
to Red Line as the Ford authorized supplier. Changed the pulleys on the
harmonic balancer and the water pump with pulleys from Red Line, and the
alternator pulley with a pulley from the local parts house. Red Line said
they are industrial engines and the pulleys are only found on them. No
problems since. Since I, unlike you, have a brain. I know what the problem
is!

So, you are saying that you are 100% positive that it needs new
pulleys?????
You haven't SEEN them, nor heard them, nor seen the condition of the
broken drive belts, and because you had a problem with YOUR pulleys,
that you can diagnose his engine just from him saying his belts break
prematurely?????
And THEN you have the audacity to say I have no brain, and you do???
This is too funny!!!!
