Re-power to 400R , prop suggestions?

Currently have a 2022 Blazer 675 Ultimate Bay Flats Boat. 2022 Merc 300 Pro XS with TM case and 1.75 gearing. Going with new Merc 400R V10 with 1.60 TM.

Right now I turn a Hydromotive Quad IV 24p at 6000 rpm and a Labbed Bravo XS 25p at 6k as well. Boat is a mod V and weighs 1850lbs. I can not turn either prop to the limiter. Doesnt get a lot of bow lift with my current setup. With the amount of torque on the V10, what would yall suggest I try first prop wise? Im guessing this will be a low to mid 80's boat with the new motor. I am willing to spend the money on the right prop. Boat has TM on bow and a couple graphs. It is a fishing setup, not a sport boat setup. I want to have top performance without having to strip everything out of it to get it to run. It wont be loaded down like a sled though. lol.

I should have access to a Max 5 ST 27p , in addition to my current two props. Interested in any opinions.

Kenny, I would try what you have first. With more power and taller gear you might not be very far off. You will gain enough info to make a good next prop selection.
