"We run a 33' Worldcat and have been losing power and RPM's on one of our engines. We have run the boat for 4 seasons now and have had the problem for 2 of the 4. We had a Honda mechanic look at this problem several times but is unable to come up with anything.
2 years ago I noticed that I had to start running the starboard throttle further forward to ge the same rpms as the port. It has gotten to the point where I have to run the stbd throttle wide open to get it to run at cruise of 4000 rpms. I tried running the boat on just the port engine (good one) and I got 17 knots (it roared like a healhy engine) Then I just ran the stbd engine and only got 13 knots and it sounded much weaker. No sputtering or hard starting, just feels week and am losing top end RPM's.
What could be causing this engine to get weaker? What tests can I perform before we take it to someone?
Thanks for your help.
