Hi,

I am not sure what is wrong, but I have changed spark plugs, but with no change in performance. I drained the bowls on the carbs, changed tanks. It will come up on plane, but not as quickly as before. I know it either the ignition or the carbeurator, but which one.

I ran the engine with the boat tied up to the dock, and it pulled strongly.

Any ideas?

Compression test is the first thing to do.
