Mariner/Yamaha 4 hp

[tshoerichs]

I have an old Mariner 4M 4hp outboard. My question is, can I change the prop to a different pitch? I am not reaching optimal rpm with the current prop I have. I cannot find anyone who lists a prop for this engine. Any suggestions?<br />Thanks.

Try the Mercury marine website, and see if the parts breakdown lists any optional props for that model.

Fouled Plug,<br />I tried the Merc site, but they don't even list that model. I tried the Yamaha site and they don't list it either. I know I bought a new prop in Baltimore when I lived there, but I don't remember where I got it. I guess I'll have to go to a Merc dealer and ask them.<br />Thanks.
