    Stuck Prop Nut

    I received my new prop this week but cannot get the old one to loosen. I've tried several different wrenches but nothing will budge it.

    This is a new motor (250 pro xs 4 stroke) that I've had for 2 weeks.

    Any tips?

    I tried a metal prop wrench and a hammer to jar it loose and it won't budge.

    Maybe a dumb question, but are you turning the correct direction?

    Lol yes I triple checked this. I'll give the breaker bar a try.

    If you get a 2x4 block and wedge it between the prop blade and the cavitation plate, remove the cotter pin (or keeper washer), get either a breaker bar or a nice longish torque wrench, it should come right off.

    I wouldn't use a torque wrench for anything except torquing a nut.

    Try some penetrating oil overnight then a breaker bar.

    Unless you hate your torque wrench....
