Hi, one of my engines (Yamaha 85) shuts down when I put it in gear. I changed the racors, the engine's fuel filters and the spark plugs and used the boat today and same thing happened. The engine is flooding with gas because if I start it up and let it idle for around 5 minutes it will stay on and as soon as I put it in gear it will shut off. To start it I have to accelerate it a little bit in neutral and it starts and it smells like gas and if I accelerate it more in neutral I can see oil in the water. A test that I did was turned the other engine off and with that bad engine I tried to plane and it will not pass the 3000 rpm, if I do the same thing with the good engine, that engine will get to 4000 rpm and using both I can notice that the good engine has to help the bad engine to plane the boat.
I took off the carbs and opened them up to see if one of the floats was sticking but all were good. I also cleaned them with carb cleaner.
I took the lower unit off and the shaft was covered in oil.
Two persons have told me to check the fuel pump. That the diaphragm may be bad.
What do you think it can be??
Thanks Mike
