Average Customer Review for Propeller Nut Kit - Sierra
Based On 1 Review
SS Propellor by Donnie - Seaside, OregonJuly 26, 2013
I have always used aluminum propellers but had issues with my takeoff speed. My prop would cavitate and it would take forever to get up on plane and go anywhere. I tried the 4 blade Stainless Steel prop and if my boat had tires it would spin them. My takeoff is quick and I am gone in a fraction of the time I use to take with the aluminum prop. I am very satisfied and it was well worth the price.

works well, i think by John - Temple, TexasMay 08, 2012
i only have one problem with this and that is the plastic washer. With the prop i recieved, there is not enough room for the washer and still get the nut tight enough for the cotter pin.

Good quality that I have come to expect from Sierra. by Ray - Sequim, WashingtonAugust 24, 2013
This prop nut kit is a good deal if you need a new castle nut, spacer and cotter pin. I basically wanted to start over fresh and all new with my new prop.
