I have a prop that I need to replace, all I can read is the number 852165, "Volvo" "R" and "15 1/4 x 17" but can't find any info anywhere online using this part number.
If the prop is aluminum it won't be magnetic if stainless it will be magnetic.
Stainless props are slightly more sophisticated than aluminum and cost about 3 times as much.
If you look up 17" props for your motor and leg they should be correct. also if you give us the info requested in the stickys at the top of the prop forum we can probably help you out.
And finally a prop shop should be able to repair your prop if its just dinged up.
