Just installed with 240 engine hours on 20' gw. Engine runs all the way to wot on earmuffs with no issues. Under load in water it won't go past 1600 rpm without stuttering. Have to throttle back and engine runs fine in idle. Can't get on plane. Engine warning light on smartcraft has continous beep.
Replaced all filters, cleaned fuel water separator. Replaced low pressure fuel pump. Tested air pressure. Tested engine on an auxiliary fuel tank with fresh gas same issue. New waterpump, waterflow is warm not overheating. Any ideas?
