Good to know. Ill check my 30 hp Yanmar. Last sumner running at WOT for 1/2 hour the motor shut down. It restarted easily and ran fine. I cleaned the fuel strainer but found no issues. Ill replace the air filter.

How the heck did the old one get that clogged? Bad decade for mosquitoes?

I had a new Yanmar air filter on the boat which I got last year, which I thought what harm could a new air filter do....changed out the old one and replaced with new one, and guess what, in neutral, the engine revived up to 3,400 before i stopped....ran the engine in forward gear at the slip for another 20 minutes.... shut the engine off...started again...revved up and down....engine works as it should. The problem was a lack of air....explains where the smoke was coming from....incomplete combustion...now, with the new air filter, no smoke. Thanks to everyone for thoughts/possibilities of what might be the cause of my engine issue. Going for a sail tomorrow. Rob Abbott AZURA C&C 32 - #277 Halifax, N.S.
