Anybody have the 22hp predator on a mud motor frame? Got this engine shortly before season started
only had it on the water probably 4-5 times since season started and each time it runs worse.doesnt want to run full throttle without acting like it's starving for fuel.bubble does get Kinda soft so we tried swapping it.can squeeze bubble when it starts cutn out and it'll pick up and run on out.but a diff. Fuel line and bubble doesnt do any diff. Read that they are bad about when under a strain it forces oil into the carb also. I know one thing,to be a brand-new engine it shouldn't run the way it is.Anybody got any input? As if now this engine is goin back this week.my kayak has never failed.

if it losing prime check all fuel line connections could be sucking air. low pressure electric fuel pump should keep it primed if connections are good. if engine has a fuel pump on it. it could be bad. if engine does not have fuel pump on it and your using remote fuel tank u will need a fuel pump.

Thanks bud.saw where these engines have a diaphram and can not pull a vacuum over 15 inches so she gets a electric fuel pump.
