3.7L Alpha One prop question

[badkins50]

I have a 1984 470 with a 3.7L Alpha One Sterndrive and was wanting to get a new prop and use my current one for as a spare. What would be the correct way to determine the right prop I would need for the replacment? I know it's a 3 blade and I'm more concerned with having a better low end than top speed. Thanks in advance for your help.

You probably should be in the prop forum, but this is a pretty good calculator: http://www.turningpointpropellers.com/

Thanks for the info. I didn't even see that forum.
