2001 21V Belts wearing out quick

[Nathan2861]

I have a 21V 2001 with a 350 MPI and the belts are getting riped up and wearing out fast. Ive replace both idealer pullies and clean out the gruves on the hole system. Can anyone give some advise on the problem or a solution to the problem. It will eat a belt up about 1 to 2 months.

Have someone check the elignment of your pulleys. Mercury put a service bulletin out on this in June 2002.

Do you know how to check the elignment or do i need to take it somewhere?

put a straight edge across the face of the crank pulley and alternator pulley. it should sit flat on both. the alternator probably needs shimmed out approx. 5/8".

Have you had the same problem with your or has anyone had the same problem. Thanks for the input.

probably close to 100 engines. talk to a merc dealer, there is a service bulletin for the fix.
