SS Propellor
by Donnie from Seaside, Oregon on July 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.

Good quality that I have come to expect from Sierra.
by Ray from Sequim, Washington on August 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.

works well, i think
by John from Temple, Texas on May 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.

accesseries for Prop
by Jerry from Weatherford, Texas on February 28, 2012
I purchased a prop and was not sure I needed any other parts. But, I order the Prop Nut Kit anyway! My sales person, Kit Kimball, was extremely helpful and I was delighted that she went the extra mile to answer my question and get info form the prop manufacture while I was waiting on hold. The attitude and help in my fustration was wonderful. Thanks for being there when I needed you!

wrong diameter, not a good experience
by W. from McDonough, Georgia on November 01, 2011
I ordered the above kit, using the model year and model number off the motor plate. The nut and thrust washer are for a larger diameter prop shaft. I called I Boats and was given an 800 # to call for the correct one. That source claims to not carry parts for the 1983 model year. I should have been told that at the point of ordering. No idea where to turn now.

Good quality - perfect fit
by Harold from Clearwater, Florida on June 18, 2011
This kit is a must if you take off an old prop. Plus, I'd recommend carrying a spare kit on the boat in case of an emergency - keep a spare prop with you also.

Q:
I have an 88 OMC Cobra(Solas 2513-148-15 Prop) Is the correct kit? What is the difference between this and 18-3733D?
A:
This doesn't look like it will work for your motor. Contact us at the number at the top of the page with your model (3.0, 4.3, etc.) and we can verify.


Q:
Whats the difference between this and 3733D?
A:
The "D" at the end of the part number just indicates packaging. Same parts.


Q:
Is it for a 15pitch?
A:
It comes down to engine not the pitch of propeller.


Q:
Which prop nut kit fits 2016 etc 150 hp HO?
A:
We do not list it, you will need OEM number 0434153.


Q:
I would like to order a prop wrench. Do you know the size of the nut?
A:
No there is no size listed for the prop nut. We will need to match it all up by engine application.


Q:
Have a 1978 evinrude 175hp v6 model number 175849C Will this work on my motor?
A:
We don't have a breakdown of your specific model number, but this does fit a 1978 175 HP Evinrude motor so it should work.


Q:
Will this fit 15 spline?
A:
We will need to know motor to match up the prop nut kit.
