I have a 1991 4.3L OMC Cobra. It starts fine and runrs fine first thing during the day of boating. However if I stop to swim or eat lunch it cranks but does not want to start. Does anyone have any experience with this that could direct me where to start trouble shooting.

Thank you.

Is this boat new to you? What are your starting procedures for a warm engine?

Yes this boat is new to me. As for starting procedure when hot. I normally try to start it in neutral by turning the key. Sometime I give is some choke and somtimes I put the lever in fast idle, but am always careful not to flood the engine. Today I found that the flame arrestor was extrmely dirty so I am working on cleaning it. I was going to check the fuel filter but am trying to figure out how to get to it. Any ideas on trouble shooting would be appreciated. Thank you.

How do you "give it some choke" ?

I give it some choke by moving the lever down to the halfway position. Is that not the choke position?
