    Help with Changing Prop on 15F

    I have never changed a prop before but my friend got a new one for his 15F. What direction to loosen the prop? I have the tools but want to make sure I'm not tightening instead of loosening. Help me out if you can. Thanks!

    The threats are reversed, instead of counter clock wise to loosen , you remove it as if your tightening a normal fastener. Be sure to check the torque specs. Don't want to over tighten it and cause it to bind up. .. good luck bud .. watch the knuckles too. lol

    yea, and you need a prop tool to remove it as well as a torque wrench.

    These are new parts,so they are already "apart". What is the correct method to torque the prop back on? Seems like the engine itself would tighten the prop on take off

    If you break the torque before removing the pump from the ski and shaft you may be able to do so without a prop tool. The shaft could be held with a fabric strap wrench around the rubber damped flex coupler. I've done this before on seadoos so the method might work.

    Maybe I am not being clear.

    How do you tighten the prop when putting it back on during REASSEMBLY?

    Thanks

    put the pump shaft in a vice and get an impeller tool for $15 and tighten it up. Yes you could use the engine to get it tight, but for reference the torque spec is 75 lbs.

    Same way with the pump installed but use the torque wrench with a crows foot adapter. Torque the shaft into the impeller with the pump installed on the ski. There is a minor calculation needed for the added arm of the crows foot wrench (for the torque wrench set value).
