Undetermined
by Darel from Kaneohe, Hawaii on February 25, 2015
I bought this product thinking it would fit my Alpha 1 Generation 2 stern drive however I needed a larger size. I haven't taken it out of the package so I gave it a neutral rating of 3 just on the looks and feel.

Propeller tab washers
by Lester from Houston, Texas on June 11, 2014
They were just like the original and it was cheaper to buy the pack of 10 from Iboats than to buy two from the dealer. Now I have some spares for the other times I change out a prop.

by Eric from Alpharetta, Georgia on May 17, 2013
Easy replacement, in fact I took the existing lock tab off of the prop and replaced it with one of these because these have the easy lifting loops. Does exactly what it is supposed to do.

Gave the motor serial number and got the prop right, but the propeller nut and thrust washer did not match the spline pattern of the prop. Thanks, I'm without a boat on my vacation. And this site won't let me choose 0 stars .... you deserve negative. Go elsewhere fast!

by a Customer on October 21, 2008
Good prop nut.
Was this review helpful?

A:

Q:
How do i replace item?
A:
Identify the OEM number and see if it cross references with this part. If you need some assistance give us a call at 1-800-914-1123.


Q:
How do i replace item #2 speedometer tube? Does it just screw into the housing?
A:
This is a prop nut for the propeller not for speedometer pitot tube. Those tubes just install on the stern of your boat with a basic hole pattern and screw it in. If further assistance is needed call us at 1-800-914-1123.


Q:
My new prop is a 1/4 inch to far up the prop shaft. The old prop had no spacer, does this washer make the new prop fit right or do I have the wrong prop?

These tab washers are for keeping prop nut secure. These do not act as spacers or anything. You will need to contact us with your motor and prop number you have for us to look into a possible issue. Call us at the number at the top of the page.


Q:
Is fit for my Mercury 75hp 4 strokes motor?
A:
