I have a 98 Yamaha C90 that leaks the mix oil when it is setting. I have had it to the dealer and they can't find anything. No cracks in the oil tank and no loose or worn hoses. Anybody got a suggestion???
I have a 96 75 merc that was leaking--it was coming from vent on top of tank when motor was up--can only keep it half full so it won't leak when motor is tilted full up--would not hurt to check it
