I have a 1995 150 HP Ocean Pro. Is the seafoam safe to do on this engine ? I only have ten hours running double oil ( break in ) that was last year. This year about 4 - 5 hours on motor, that doesn't seem like a lot, should I have to do a treatment already ? By the way my marina is a 20 minute in and out no wake zone, so I am going very slow a lot, could that be reason for some extra fouling of plugs ?
