    Lower Unit Washers

    Don, You mentioned a new washer that needs to be changed to upper and lower screws when changing the lower unit gearlube. I cannot locate then around here.
    Seems I remember they were blue instead of white or yellow.
    Help please.
    Thanks, Mark

    Re: Lower Unit Washers (Boatseller)

    I just picked up a set of the new yellow ones. The dealer told me they only come in kits they get and are not available for public purchase yet. I don't know how accurate that is. They said the new yellow ones can be used more than once but to not over tighten them. I am going to install mine next weekend.

    Two different sealing washers are available:

    191833 (Blue paper-type sealing washer)
    830749 (newer "yellow plastic" sealing washer)

    We keep BOTH in stock.
