Prop suggestion for a 175 VMAX SHO

[Capt. Lenny]

Always in a search for the best all around performing prop for a Yamaha 175 VMAX SHO. I have tried an assortment of different props with mixed results. Just wondering what you're using and how you like it?

The boat is a 2001 Ranger 200C fisherman Bay Boat with a T top that weighs about 3800 lbs. (because fishermen carry a lot of junk)19' 10" long 94" beam and it's the same hull as the Ranger 620 VS multi-species. The engine is a 2015 Yamaha 175 VMAX SHO. Here's some of the performance numbers that I've gathered.

So, what am I looking for? Mainly a better holeshot when I have 3 or 4 people onboard without sacrificing much on top end. I lost the holeshot that I had with the old Yamaha 200 HPDI after it got struck by lightning. The short story is I got screwed by the marina I dealt with in Port Clinton Ohio when all this happened.

The numbers on the Enertia are rather weird.

I’m running the same prop on a #5200 Grady Walkaround with a 225 HP.

Get similar results with the except for the “hump” in fuel consumption, which I’m guessing is right around where you come up on plane.

I get a weird chatter right before the transition. Assume I’m momentarily powering the prop but otherwise pretty happy with it.

May drop the 4 blade, Offshore Renegade I had on the boat previously to confirm my suspection
