I recently bought a 1992 25hp Nissan outboard with non thru hub exhaust with a pin drive prop. I'm looking to replace the wrecked 9.9x13 prop that's on it but I cannot find that size pin drive prop for a Nissan. Will Johnson props work? Is there any other mfg with the same shaft size that will interchange? Also I see where it's simple on most Nissan 25hp's to convert to a 30hp. Will my 92 model convert the same way? Just a restriction plate? Thank you in advance for your time
