Hello. My name is***** the engine on a different fuel source. We need to eliminate the boat side fuel system as a possible cause of your issue. This could be debris in the fuel tank, clogged fuel vent broken pick up tube or failing anti siphon valve. All you need is a gas can and some fuel hose for this test. Disconnect the fuel line (plug it) coming from the boats fuel system at the engine then connect you gas can and fuel line to the fuel connection on the engine run the boat. Does it run better or the same?
