Just to hazard a guess, it sounds like it could be a timing issue. Does the
engine use points or capacitor ignition? With capacitor ignition, you'll
have to swap out the capacitor to see if it fixes the problem.

Help with boat problem
----------------------------------------------------------
I have a 140hp Mercruiser engine in a boat I just got ,,I was wondering if
I could get some advise???

My boat runs great for about 1 hour,
however as soon as I start allowing my
kids to ski or tube , and I go from drive to neutral , and back to drive a
few times the boat wants to die.. like it is running on 2-3 cylinders, not
all 4....

I was able to run the boat fine with , the problem seems to only happen
when
I go in and out of drive several times and when the boat has ran a while

I changed the neutral safety switch on the side of the engine.. ( I was
told
that was the problem) but it still does the same thing... any idea's
I do not believe this is a fuel problem
