Answer 1

Try using a bigger sail.

Answer 2

clogged fuel line, plugged pump or suction ports in the water lines,  check for foreign objects in all of the above and repair as necessary

Answer 3

its probubly old, try getting a new one or take it into some boat store. the engine is probubly fried

Answer 4

and check for spark on all cylinders, one might be dropping out.

======================================...

"All the clyinders have spark all the gas lines are flowing good all the way up to the carbs."

In that case, a carb rebuild is in order.

I'd do a compression test first though, easier and might save you from wasting time.

Answer 5

Polaris has fuel starvation problems mainly to the front cylinder. The fuel pumps are rather weak, and tend to starve the front (furthest from the pump). It is possible you have siezed the rings.
