90 Hp Force Stalls Under Load?

[dabutcher]

MY BOAT STARTS UP QUICKLY. THEN I TAKE IT TO LAKE AND WHEN I RUN IT UNDER LOAD IT STALLS. I DID A COMPRESSION TEST. TOP CYLINDER 122 PSI ,2nd 13 PSI AND THIRD IS 118 PSI. SO TO ME WITH MY LIMITED KNOWLEDGE I WOULD SAY MY SECOND CYLINDER IS IN NEED OF REPLACEMENT. I WORK ON MOTORCYCLES A LOT.NO INTERNAL MOTOR WORK THOUGH. IS THIS A REPAIR THAT I COULD DO MYSELF IF I HAVE A SHOP MANUAL? OR DO MOST PEOPLE LEAVE THIS TYPE OF REPAIR TO THE EXPERTS? THANKS, DARRYL

This is something I would try with my experience being similar to yours. Don't feel ashamed to take parts to a local machine shop with marine engine experience for assistance. Overall it can be a rewarding, albeit time consuming, experience.

Good Luck!
