1985 Force 85hp. I replaced the fuel pump diaphragm. It Ran before, up on plane and all, just not very well. When replacing the spark plugs the third cylinder, bottom one, always did not show ware/combustion. Spark was good so I asked on here and got the suggestion that the fuel pump diaphragm is leaking and flooding the lower cylinder.
I opened the fuel pump and the diaphragm had a tear. THERE YOU GO I SAY! I replaced the diaphragm and gasket. Now it starts fine but as soon as I try to launch it dies. ??? When I replaced the diaphragm, I tested at home first. Started fine then it blew the hose from the fuel pump to the carbs off. I thought, this is good! New diaphragm is working - more pressure. It idles okay, but dies when I put it in gear and try to give some throttle? Any help would be GREAT !!!!!!!!!!!
