I dont have compression test, jet weren't touched and spark dose jump at least 3/8" this is normal a 50+ mph boat only started having this issue after boat sat for about 3months with no use.
Engine will start an idle fine except when I press hotfoot to accelerate the boat will only go anywhere between 11 and 29 Miles all spark plugs , wires, and coilpacks were changed Carburetors cleaned but jets were not touched Any suggestions?
