Item: S15409
The components used to secure a propeller to the prop shaft are realistically only designed to be used two times, after which they should be replaced. The max torque when tightening this nut on the shaft should be 35 ft/lbs.
This kit includes everything you'll need when changing the Acme propeller on your boat:
Aren't sure what size you need? The shaft size you select for the prop hardware kit needs to be the same as the propeller you have on your boat or are purchasing. If you are unsure about your prop shaft size, use our prop finder tool to look up our suggested props for your year, make, and model boat.
*Those ordering the spline version for 2003 and newer MasterCraft boats will not need to use the key that is included in the prop hardware kit.
Note: This hardware kit will not work with older style shafts that make use of a castle nut and cotter pin arrangement. These are typically found on boats from the late 70's to early 80's.
Everyone should spend a couple bucks on this. Stash it on the boat in a ziploc and not worry about a lost prop nut or keyway.
I keep a spare on board “just in case”. A little peace of mind.
I bought this with the puller for the spare prop I hope I never need, should last forever.
Works as expected, I didn't end up using the new Keyway that came with the package though...it was considerably shorter than the stock one that came with my 14' SUPRA SC 350.
NOTE: Thank you for the feedback regarding the size of the key in our replacement kit. Based on other feedback we have switched to a longer key with this kit which should be a direct replacement for the key that came on your boat.
