I talked to my brother in law yesterday regarding my new boat ('98 mirrocraft w/ 40hp mariner). He was saying some people recommend having the oil injection system "cut off" and just add the oil to the gas by yourself. He said beings it is a newer engine right now, not to get real concerned at the moment but it might be something to look into. what are your thoughts on this? Also what are some good signs to look for when the injection system might be failing and need repair, minus a siezed engine!
