I'm wondering the difference between a 14. 9 ne 14.10 prop I have a 1971 f/25 with the 225 Chrysler.

The 14 x 9 will give you a higher WOT rpm than a 14 x 10. It will also require a higher engine rpm for a given speed. What prop do you currently have?

FYI, Trojan did not produce the F25 in 1971. In 1971 Trojan produced the F26 and 25 Sea Raider. The Sea Raider had a fiberglass hull and wooden deck/superstructure. Does your boat have a fiberglass cabin or a wooden cabin?

It is a wooden cabin. Would that be a 1" prop shaft on that? And would you know the rotation?

A 1971 with a wooden cabin means you have a 25 Sea Raider. It has a 1" prop shaft with RH rotation. If you PM me your email address, I can email you some information on the 1971 25 Sea Raider.
