I did my own impeller replacement in the fall (Oct). Then filled with fresh Merc green syn lube. Then winterized engine and fogged. Stored boat all winter with drive down. Picking up the boat today I noticed a film of oil on the right side of the outdrive below the case split. There looks like a weep hole. There was about a three inch by half inch spot that was enough just to wet one fingertip. After wiping it with my finger it is green -- the same color as the outdrive oil.<br /><br />I know the carrier is on this right side. Possible that the o-ring did not seat properly? Or is that much seepage normal for 5-6 months?<br /><br />Should I drain the oil, split the case and double check the o-ring?<br /><br />2001 Alpha 1 Gen II drive.<br /><br />Thanks!
