  • What prop is this really
    Part number on prop is 48-73132-10.

    One site shows: 15 DEGREE PROGRESSIVE PITCH -- Used on Mercury outboards, 35 HP through 140 HP. Usually have a 3 inch progressive pitch. Stainless steel and aluminum propellers. Doesn't mention diameter.

    Is currently on a 1999 40HP Force (pushing 20 ft pontoon). Might be slipping and if so need to replace.

    Pitch is expressed in inches. Usually the number at the end is the pitch 10 Might be for a pontoon.
    Usually slip is the difference between theoretical speed and actual speed. Expressed in a %.ie.10 % slip.
    The prop losing grip is ventilation The prop becomes air fouled.
    If the prop is defective with a bad hub its called a spun hub. Ventilation and a spun hub seem the same
    but ventilation may happen at at different speeds or triggered by waves,while a spun hub usually happens at roughly the same power range.You can check the hub by putting a water proof line across the hub and doing a test run.Line will be broken if hub is bad..
    If a smallish prop probably a new prop is more cost affective.
    Pretty sure the 99 Force uses a Merc prop and has a Merc leg.
