Go ahead put a 3 blade on ! Go from 2 blade to 3 you need to talk to a prop compan They can tell you size and pitch.

When you talk to them you need to be able to tel them boat weight, engine RPM max and transmission ratio, and left or right hand prop

Tom,
I have a Hunter 2003 356 and just went through the same exercise. Went from fixed 2 blade (original spec) to fixed 3 blade. Did not want to dump a bunch of money into a folding prop so settled on a Campbell Sailor 3 blade by West by North Industries located in Canada.
This prop almost always comes at the top of the list for fixed 3 blade props for a mix of thrust, reversing power and low drag (relative).
Have the 27 HP Yanmar with 1 inch shaft and fitted a RH 15x9 prop BUT would have them spec out the correct model for you dependent on boat model, engine size and transmission gearing.
Splashing next week so I can't tell you how well it works but am looking forward to finding out.

Like the post above, I put a Campbell Sailer [sic] on my 32-ft. Catalina w/29-hp diesel, and it works well...better thrust and minimal drag (for a 3-blade).

But you gotta contact the company for its (much-better-experienced) recommendation on size and pitch. Clearance could be an issue with larger-diameter prop.

been there done that, started with a Yan 3GM on a C&C 36, with a fixed 2 blade- poor performance + vibration, changed to a 3 blade Michigan sized by the factory- was like dragging an anchor- lost at least 1/2 knt under sail, shifted to a 3 blade Campbell sailer - a bit less drag but generally compromised performance in forward and reverse, changed to a 2 blade flexofold, - good performance but vibration again, they gave us credit towards a 3 blade which finally is the real deal at a lot less money than feathering props and no maintenance issues after about 8 years. If you never sail then a Michigan 3 blade is fine.
Good luck, Emile
