The pulley you asked about is no longer manufactured. Mercruiser has changed the belt system.
The attached bulletin explains the changes and the new kits that you have to use depending upon
which engine you have. Sometimes I wonder if these are excuses to charge more, but in this case
the new belt and pulley system does improve how long they last and gives better performance.
If you can’t figure out which you need (as the bulletin is the most clearly written document) just let
me know what engine you have and I can get you a quote.
