I have a 2004 Marine Power 335 EFI engine that knocks quite loudly starting at about 2000 rpm. Last fall it did the same thing and the dealer "cleared an error code" from it and it ran fine after that. We'll now its back. Anybody have an idea on what may be causing this? The engine runs great at low rpm & at idle.

Any idea what code it had?"I refuse to answer that question on the grounds that I don't know the answer." -
sorry switchme, that is not near enough info to trouble shoot the problem. you need to call that dealer and find out what they fixed or didn't fix. there should be some sort of record of what they found wrong.Greg Denton
