Hunter Edge powersailor hybrid prop selection

Greetings - excited to acquire a Hunter Edge power sailor with the 75hp etec:


The present prop (#763300 - 14x9) yields 4700rpm WOT.
I see the Hydrus series has a 13-7/8x9 available (#177201) - might that 1/8" less diameter yeild slightly higher RPM closer to the desired 5000?

If a 4 blade Rogue supposidly boasts less vibration perhaps that would be ideal? (presume 13x17?)

Hunter Edge is a heavy beast... approx 6500lb with ballast/crew/gear, 5000lb ballast out.

Re: Hunter Edge powersailor hybrid prop selection

That is a very heavy load for a 75 HP and the motor will need a shallow pitch prop to achieve its operational rpm.


Propping is trial and error and the Hydrus series prop is made for pontoon boats that also need high thrust at lower speeds and good backup response. Give on a try in the smallest pitch which is 9"


Your goal for that motor is at least 5000 rpm at full throttle - 5200 to 5500 is even better for your application.
