The 50 hp is a fantastic motor but you should be made aware of one problem with the non vented fuel tanks. If you leave the fuel hose attached to the tank and motor in the sun, the fuel in the tank will be pushed into the engine filling the crankcase with gas. The oil dipstick will show that the oil level is too high. A person should run premium fuel as well and the engine is such a fuel miser that the higher price of premium fuel is negated.
