Thank you for looking.My son in law has a 94 40hp model # E40TEERE that has a weak spark on top cylender.I have changed plugs,rebuilt carbs and fuel pump.The vro lever is in correct posistion.I checked both coils with a continuity tester and neither has a dead short.Moter will idle fine,but will start sputtering at half throttle.Out on the water,it will fall on it's face and not open up.
I also checked compresion and it was fine on both cylinders.I also took the carbs back apart and things looked good there.
what else can I check?thank you.Mike
