Welcome Aboard.
Do I understand that you bought a boat with no prop on it? How did you sea trial it and how did you get a comprehensive survey done?
If it has a prop on it but you are unsure if it is the right size, read up on the engine, determine what the W.O.T. is supposed to be and see if you achieve it under load or in neutral. Go from there.

sapple, Don't worry about fitting in here as the rules are simple. 1) Don't start a thread about anchors & 2) Don't comment on how to mark anchor rode. Search those subjects first!

Welcome aboard. Congrats on your new boat. Are the current props not marked? They usually have a stamp on the hub as to what the diameter and pitch is. As said before see what WOT RPMs you get before doing anything. Then if you are not able to get the proper RPMs then a prop shop should be able to recommend what size you need to go to. They will need to know what you got for RPMs at WOT and what size your current props are. They can scan the props to see what size they are if the props are not marked but you would have to pull them and take them to the shop. Call first and make sure they have scanning equipment. Good luck.

I have DeFever 44. It came with 25 x 20 props if that means anything to you. With a full load of fuel and water the boat reaches 2,350 RPM with a clean bottom. It may be slightly over-propped as the FL120s should ideally reach 2,500 RPM. It does not concern me or would it for many others here on this forum.
I am curious, however, why you would determine to replace your props without knowing what the diameter and pitch you have. As for spending new money to have spares on board, that would not be something I would do. There are so many other ways to spend boat bucks. Your DeFever has a full-length keep giving good protection of your props. Having spares, although for some would be peace of mind, on your boat would be a very expensive just-in-case. Others here may have a different opinion.
