With 20" mids, if mounting the motors directly on the transom, mount them as low as you can. The prop shafts will be about even with the bottom of the boat. If running the ocean a lot you may want to consider hydraulic jack plates so you can run the motors deeper when it gets rough.

You will have a better cruise with Bravo's and better top end with choppers.

I'm actually running mine with Bravo's right now, but switching to choppers for next season.

i didnt use jack plates because i wanted to keep the balance of the boat. with the weight of the motors i have on plus the jack plate i think the stern of the boat will be to heavy. the boat had on 260 + jackplates,without the jackplates on now is jus a couple lb heavies. trying to keep the boat the same weight like from factory. what size bravos or choppers should i run? my gear case is 1:62. thanks

With 1.62's, I would try 24" pitch props first. If you can pull them to 6800 rpm's and are set up correctly you will see 85-87 mph.

Call BBlades. They have a prop exchange program. If the 24's are not enough you can exchange for a set of 26's.
