I just replaced the tank on top with a pulse fuel pump and replace the intake and exhaust .runs way better at the 5000 feet elevation . I now have a 4 gallon fuel tank on the floor with a priming bulb on the fuel line . It took a lot of weight off the transom greeting rid of the tank on top ,heavy exhaust , bulky air filter and cover . Way better air flow and fuel flow .gravity fed fuel from the tank on top did not keep up and the engine would starve .
