Great Quality, Price and Timely Delivery
by Michael from Ann Arbor, Michigan on June 30, 2015
I am extremely happy with this purchase, along with the propeller. I had entire order within three days as promised. My boat is happy too. I ordered two propellers instead of getting my old one repaired because these were so reasonably priced.

Propeller
by Erling from Abbotsford, British Columbia on June 21, 2013
I was not sure what propeller and nut I needed for a 1973 Mercury 650 after loosing them. Called in and their support was very knowledgeable and helpful. When the parts arrived, they were a perfect fit.

Its a nut. It fit on there as it was supposed to
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.

by BOB from Industry, Pennsylvania on July 23, 2011
I WENT THROUGH THE WEB SITE PROCESS TO ORDER THE PROP I NEEDED AND IT AUTOMATICLY OFFERED ME THE OPTION OF BUYING THE PROP NUT AND OTHER ACCESSORIES THAT GO WITH THE PROP. EVERYTHING ELSE WORKED BEAUTIFULY BUT THE PROP NUT WAS TOO LARGE. SINCE IT COULDN'T BE RETURNED IF OPENED I JUST USED THE OLD NUT AND TOSSED THE NEW ONE.

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?
A:
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:
We will need to know the serial number in order to match up the part.


Q:
I have a 1996 Force 120 HP outboard with the 4 1/4" Mercury gear case. Which propeller nut kit do I need?
A:
This prop nut kit is the correct one for your motor.
