I recently bought a 17' Starcraft CStar and the manual for the motor says to use 10w40. Will 10w30 do or should I stick to this grade? It seems to be hard to find.
Also,the manual says to replace the water pump every year, is this true? I've never winterized a 4 stroke before. Would you have some guidelines? What do I do with the fuel. On my 2 stroke I put stabilizer in the tank, topped it right up and disconnected the fuel from the motor and burned it all up.
