I am having an intermitent problem with this engine in my boat.

When I run at around 2500-3000 rpm and do some modest "wave hopping" in
Southern Georgian Bay, occassionally my engine just "dies" (stalls).

When I restart it and give it some throttle, it behaves like it is either
"fuel starved" or being "flooded".

Usually, the "fix" involves stopping the engine, opening the engine cover
and pumping the fuel bulb until line pressure is restored, then restarting
the engine and running up to 2000 rpm @ idle, THEN re-engaging the
transmission (which usually behaves normally then).

My mechanic cannot figure it out (without much expensive "diagnosing").
Besides, being the height of the season, I am likely to have to wait till
mid-september before he could run up my bill.

Any ideas?
