What size Prop Do I Need

[LittleBoatThatCould]

I have a 1974 9.9 evinrude on a 14ft fiberglass mannix, hub is spun, Im just going to purchase a new prop, how do I know what size to get, I looked it up on this website under prop finder and shows 3 different sizes 10x5, 10x7, and 9 1/2x10. Thank you!

Why not just get the one you have rehubbed, LBTC?<br /><br />If your performance has been satisfactory and you want a spare, just duplicate what you have.<br /><br />Good luck.

I dont know what I have now though, this is my first boat, before the spun hub performance was great I dont know know what is on there now, or what to replace it with. Would there be a huge difference between using the ones I listed.

Yes, LBTC. The performance could change drastically.<br /><br />Take your prop off and take it to a prop shop. They can rehub it for you, and they can tell you the pitch to get for a spare.<br /><br />Good luck.
