I have a 2000 Pro Deep V-17, with a 90 horse Merc. Running at 5400 rpm at WOT. My question is, i want to go with a stainless steel prop. Prop numbers are 12.75 x 21 on my Alum prop. On the lower end there is a sticker that says 13 right by the prop. Is that the biggest Dia. i can go for this motor. If so most props i have looked at are 13 1/4. Also should i stay at the same pitch of 21 when going to SS.

Thanks Bill.

If the ss prop is larger in diameter I would/did drop 1" of pitch. I was told to drop 2" of pitch but 1" worked great for me on my 50hp. 10x15p alum gave me 5400 rpm@wot, the 10.5x14p SS gives me 5400@wot and I swear I have more topend and alot less steering torque....Jerry

Thanks for the info. Still have question about the sticker on the bottom of lowerend unit says 13 is that the highest diameter i can go. Most of the props i looked at are 13 to 13 1/4 diameter.
