What kind of oil does a kawasaki 650 jetmate boat lower unit take?

Hopefully you have not put oil in the crankcase.....The only place two stroke mix oil should be placed is in the polyproplyne container next to the engine....also if a previous owner has removed this poly tank.....and blocked off the automatic mix system....then you will have to premix the fuel.......would recommend this in a separate container to minimize spills before fueling the Jetmate
