WOT is about 5100 rpm. 5750 rpm is max for my motor, wanted to try a 19p, but I may have to go down to 17p

Don't waste your time with a 19p prop, it's too much pitch. If you drop from a 21p to a 17p, you should pick up at least 400 RPM's. That will put you right close to the 5750. I'll sell you my 13 1/4 x 17 prop with the hub kit for $100 shipped if you are interested. I can send pictures of it if you like. I don't think there's a mark on it. If it doesn't work out for you, I'll return your money less any shipping costs.

Stainless. Looking for 17p ss

Okay, it's a Mercury manufactured prop, part # 7744445p 13.25 x 17p. Here's a picture of the brass spline piece part # 826074. There is another big brass washer for the back, which I have, but it's not in the picture. PS, there are a couple scratches on it, but not from hitting bottom or anything.

prop looks good let me see if I can find out if hub will work on my motor, guess that is grease on inside of prop ?? mine must not have any thus why it is stuck.

I've had the prop advertised on another local board and now have an interested buyer. Haven't heard if you want the prop on not, so I'm going to offer it up the the fellow who's interested.

if you can sell it go ahead, I'm doing some research to make sure what will fit my motor.
thanks Shellback
