Correct thrust washer, prop nut, etc

[capt_mike]

Hi all,
I have a 1987 175HP Merc that I am re-propping. I purchased a Mercury Vengeance prop (48-77402A4 25P). What thrust washer, prop nut, etc., do I need to put this prop on my motor?

Thanks,
Mike

Re: Correct thrust washer, prop nut, etc

If you have the prop in hand, remove your old prop and install the new one. Install the lock washer and tang locker plus nylon inserted SS nut. If you can get 55 ft lbs of torque on it and have one or two threads left behind the nut on the prop shaft, and the prop spins freely even when you push in on it you are good to go. If not you will need to worry about getting the correct washer.

Some of the new replaceable hubs require a different thrust washer as they apparently are of a different hub length dimension from the rubber slip hubs. If you buy a prop on iboats they list such just above the prop that you select.

HTH,
Mark

Thanks Mark,
Had to get the correct lock washer but everything else worked fine.
