Alright recently I just purchased a tri hull boat with this motor on it. It will run fine on high idle but I can not get it to run without being on high idle which is bad because when I engage it into forward it jerks and for a 50 hp it is not going as fast as it should and most of the time it will shut off. I have brand new gas lines and just rebuilt the carbs hoping it would fix this but it did not and I also changed the plugs
ANY ideas would be greatly appreciated!
