The engine runs great sometimes and sometimes rough at lower speeds and half speed at full throttle.
It could be a fuel pump or it could be the water pump. If the water pump is not doing well the guardian system kicks in and lowers the speed.
Would the fact that it runs good when going out but after we set for awhile fishing or whatever and start it up and the engine has not had water flow so it may heat up indicate it could be the water pump rather than the fuel pump?. I want it to be the water pump becuase they are much cheaper than a fuel pump. But you know how that goes.
