    Lower unit 2003 mer ecu 200 ser#ot648698

    I might have broke my lower motor runs but will not engage the prop when
    You put it in forward Was running at about 4800rpm and it fell like something
    Gave and just quit....motor didn't just the prop. Motor runs just no spinning of the prop
    So how can I tell without taking the lower off. I will be shopping for a lower unit

    A good starting point would be to sample the gear lube... look for water, metallic particles, or metallic "sheen" in the lube.

    Should you indeed end up purchasing a gearcase, STRONLY recommend sticking with OEM. Sherm @ Sherm's Marine (or I) would be more than happy to assist, including a BBC member discount.

    Email or Phone are the BEST means of contacting the Parts Department(s).
