My pulleys are jacked!!!

[ereed969]

When I bought my boat several years ago the guy I bought it from told me that one of the pulleys had been shimmed with washers. The pulleys never looked straight so I didn't understand why he did that. It creates black dust all over the motor and the air cleaner has been sucking that. So today I took off the washers and the pulleys looked perfectly straight. I thought I was in the clear until I started me boat. The belt almost came off. I'm not understanding what is going on. I have read a little that there are others that have had this problem, but I don't know what to do to fix it. Any help would be much appreciated. Thanks

Sounds like the PO was on the right track with the shims, but maybe it needed a little more or little less. Which pulley was the one shimmed? You may have to hunt up an actual shim kit as opposed to just a standard washer, in order to get more precise result.

Not sure what engine you have, but maybe this TSB will help?

That is exactly what mine was doing... went through a lot of belts until I found what TeamAllen posted... I used to alway shred one of the rivits on the belt. Now everything has worked as advertised! I also replased the two pulleys on the top end of the motor along with their brackets... http://www.mercruiserparts.com/selec..._nbr=827680+98 try this site when referencing your motor.. just make sure it is the right serial number... might have to plug in your motor.. mine is a 2001 2100V LE.. Let us know what you find... more people have had this issue than you know..

I read the instructions that Team allen posted but I used washers. Works great now. I just ordered the proper spacers. My boat sounded a lot smoother with the alternator adjusted. Thanks Guys
