The nut you sent was the wrong size. Needed to be a 1" NOT a 1-1/16" so the washer was wrong also Propeller looks OK Haven't tried it yet.

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.
