40hp mariner
I need some help. I have a 1987 mariner 40hp on a tracker guide special. I do not know what size prop is on it currently but do know it is stainless 3 blade. Trying to find a back up but with no idea what size to get. Anybody direct me where to figure this out or have a similar set up that can tell me what they are running would be great.

Buckeye thanks for the input but I know have seen a prop selection formula that used weight hp and length of boat to ballpark a prop. I have no idea at all on the pitch currently but do know it runs alright at about 30mph. Just trying to find a similar prop in pitch.

Are there any stampings on your prop?

Nothing that I can find. I bought it last fall and before I made a trip other than local wanted a back up. That is what has me confused. Cant seem to find the stock size or any markings on this one

If you don’t have a 4 stroke it’s most likely a 13 spline.

How do you measure pitch? If I could figure this out i would just buy a replacement in aluminum and go with.
