i have a 255 sitting at the shop,belongs to a friend that has not been so good of a friend lately..in the middle of the resto he bailed so i put the boat outside with all new sbc's emi exhaust with through hulls.all new gauges and interior..he seemed to have lost interest..btw it has new gel from the water line up..if he dont pay me im going to part it out..
anyways the boat liked the laser II props, the cleavers seemed to not let the boat plane so well,we pur the laser II on and the boat jumped on plane..
i would stick with the 1.50 drives if you plan on using rev 4 props,i bet you will be braking the drives with the 1.6? retio..the 3 blades will be more forgiving because it wont bite the water so hard..

BTW...thanks for the info on the Lasers and I'm with you on the Cleavers...I've never had any luck with them on any Formula I have owned.

The Rev4 sounds like a good option for that hull. But then again, if your drives sits deep in the water, the M+ or LaserII props might offer plenty of bite, and good top end performance. As always, testing is a good way to find what you like. I would go with the 1.67 gears too, gives a lot of options to boot.

I defer to you guys...is that average or deeper than average on a twin I/O boat?

How deep is your prop shaft centerline from the bottom directly in front of the drive, when the drives are at neutral trim? ___--------- Top line is boat bottom and low line is prop shaft c-line, and the distance needed is the one straight down between the lines.

In that case I'm with mrfixxal. Your drives sits very deep, so the LaserII's should offer a good combination of hole shot, cruising speed and top end. If you don't feel like the bow is carried enough, or you have blow out issues with the LaserII's, the Mirage+ would be the next one to try.

I like RH/LH with M+'s turning inward, Labbed with a diameter change after a stock configuration base line.
I think you probably 8"'s below.
