When I start the boat cold it backfires every now and then and doesnt seem to get the gas like it should.Once is warmed up its ok but there is still a little hesitation.I changed the plugs and used a carb cleaner.Is there anything else you can think of,is there fuel filters i shold look for.I know its not the fastest engine but i can feel it isnt getting the gas correctly and then it goes ok.
