Having problem with my Tohatsu 5hp 4 stroke . It came with Athena for her dingy, from day 1 it ran great until you give it full throttle then it cuts out and dies. Then it will start up and run at low rpm's until you give it to much throttle.
So I'm thinking lack of fuel, so I went there the fuel system from tank, fittings, carb jets, etc. No change. Then I pulled the plug so I could turn her over easy and pull the fuel line off the carb after the fuel pump and turned her over.
No fuel pumping! Pulled the pump off and found oil behind the diaphragm, so I cleaned it out reinstalled and Its pumping fuel. Problem fixed right, No problem may be worse? Any Ideas. The motors only worth about 6 or 7 hundred so don't what to drop to much into her, but she fits the bill nice.
