Thoughts on Prop Selection - 27p for 21' Baja

Hello All -

Need some prop advice. Finished rebuilding a 454 in a 21' Baja Sunsport (shallow vee, open bow, late 80s design). Engine makes about 430hp compared to the original 365hp from a 454 mag. So here's the prop info:

Always had a 25p Turbo prop on it, 14.5" diameter, would run a solid 4800 rpms, good bow lift, no chine walk.
With 25p Turbo on new motor it will rev well over 5000 rpms, and for reliability purposes I would like to keep revs down (dyno also shows peak HP right at 4900 rpms). I would love to top out around 4800-5000.

Would like to go up to at least a 27p. Limited options up to 27 pitch, seems like mirage and turbo are standards, but not sure what else is out there? I also wouldn't mind trying a 4-blade if anyone has a recommendation.

Please let me know. Thanks.

Tony
