Need help with new prop

By jewellbox - Published April 03, 2011 - Viewed 7295 times

Hello, new to this blog.  Just repowered my 1983 SeaRay Sundancer.  Would like help picking out a new prop.  Repowered with 300hp 350 mag.  Would like to stay with aluminum.  Thank you.

This comes from Gabe Capobianchi who hosts the BoatUS " Ask The Experts" pages (www.BoatUS.com/askexperts):

With a 50 hp change on a re-power, depending on how your previous propeller performed, you may need to do some testing. Try your current propeller and see if where you stand with your WOT, ( wide open throttle ).  If your current propeller is a 14.50 diameter x 19 pitch, and you exceed your WOT then go to a 14.25 x 21 and that should work.

Let me know how this works for you,
