Is now a good time to say the comment about checking the wiper motor switch was some funny chit? If bad timing, don't read this posting. :p

Re: Mercruiser Engine Problem
 

I'm having a similar problem with a carbed engine. It dies under load. It revs up fine and doen't miss a beat in neutral, but try to get on a plane, and it dies. I've about convinced myself it's the carb, so I plan on swapping them to see if the problem follows the carb. I just got to thinking the other day, that was the engine I had out for tranny work early this year. I wonder if a fuel line got kinked or bent when pulling the engine. I haven't looked yet.

I worked on a SeaRay once with twin 4.3L that did the same thing. Finally found that the lagging engine had no spark advance. Joe, have you ever seen this?

Alpha outdrives? Shift interupter switch bad or maladjusted.

honestly not in a long time since the days of mech advance unless some one left a timming shunt in place (grounds the dist advance to set base timming )
