    Question Gear oil for Mercruiser alpha one?

    Looking to change gear oil in my alpha one drive..

    Is there a difference between normal motor oil a marine oil apart from the price, I have heaps of different types of oil in the garage for bikes, cars etc
    I cant see why marine oil whould be any different when its doing the same job?

    The only think i need to know is what weight is recommened?

    Thanks, James

    James, in my opinion it's not worth the attempting to save a few quid for an essential part of keeping an Alpha One drive worth a couple of ŁK working correctly. Others may differ in their opinion but the safe option is to go with the manufactures recommended lube.

    The manufacturer recommends oil that meet certain properties and are specifically designed for the use (eg. tolerant to moisture).

    You may skip the engine manufacturer private label oil, but should stick to recommendation. Even for gear oil (which is not engine oil).

    Use the High Performance lube James, the bluey green stuff. Some sites say it's ok to use the premium lube (bronze coloured) but I've always been advised to use the former

    Are you changing the lube yourself James? presume you know about filling the Alpha One (gen II?) from the lower drain hole if you are? Are you changing the impellor whilst you're at it?

    I only bought the boat this year and was told it was serviced and didnt need another service untill end of season, i wanted to change the gear oil as a peace of mind. Yes i will be doing it myself but i wont be changing the impeller just yet. Im not sure if it Gen I -II was made in 1992 if that helps?

    I think they stopped production of the Alpha 1 Gen 1 drives around 1991 so if I right (I may be wrong) it could be either. post a picture of the drive to be sure.

    You mean the original Merc oil, AKA "green death"?
    Beware! In this specific case, using something else is not a matter of saving a few quids, but rather of saving the outdrive.
    We discussed that in this previous thread:

    ...and you can find much more about that in the offshoreonly US forum, if you're interested.
