The boat was parked for 4 months but i start it once a month for 5 mins. with the water hose. I started it a Saturday with the hose 5 mins. and it was fine the i put in the water on Sunday morninig and it didnt want to start. I took it back to my shop and drained the fuel tank ,the pumps,flush the fuel lines and changed the filters.I put new spark plugs, new gas.I did try to start it and nothing.The throttle body was getting flooded and the fuel was leaking out of the throttle body gaskets.I removed the throttle body assy. and cleaned it and installed new gaskets. I also removed the vapor separator to clean it and checked the float. I try starting it again and it did start and ran for around 3 mins. and it shut off by itself. I notice that wasnt enough smoke from exhaust. I try starting it again and it wont start.
