My 315horsepower mercruiser is very strong and good til now
but just now with 705Hours an 1,5 year of using it begin to
when in full throtle all the way it lacks fuel in the engine and backs to idle without moving the throtle positionn.. but when not all the way down it goes normally.. my first thought was the Fuel water separator and filter, changed and keeps doing the same thing.. can it be the Fuel Pump doing this? just when the engine really needs the gas it dont work? assuming there are 2 fuel pumps one that without it the engine will not start, and the other for the high end rpms?
apreciate for any help.
