Wakemakers has a relatively good chart that I frequently default to:
https://www.wakemakers.com/supra-wak...oat-propellers
scroll to the bottom for DD boats. It recommends an Acme 422 for you - 12.5" x 15.5". In my experience with a Nautique with a 351 and 1.23 trans you'd definitely want to be in the 15ish pitch range.

Thanks for the help. It looks like the ACME 422 is the replacement.

Thanks

422 should work for you. If you are commonly running with ballast or lots of people, you may consider the 1868 which is the same diameter but 14.25 pitch. Have fun, a new prop really wakes up an older boat, or really any boat that previously had an old-style prop. Just go out for a nice empty-boat WOT run and check top speed and top RPM after installing the prop.

The 422 did the trick run just like it use to only smoother.

Thanks for all the posts.
