Ok lets hear your ideas.
 

I have a 93 35 Fountain, we just built a set of 775 hp N/A motors, added a set of new Xr's, 2" shortie imcos, and stelling boxes and mounting the drives in the highest position on the boxes so over all even though the boxes set them down an inch with the drives in the highest position we will retain the 2" high then stock X . Now the motors made the 775 hp at 6500rpm and 768 ft/lbs at 4200 rpm, at 5500rpm they make 720 hp or so and will only run the motors up to 5500 when in the boat. Question of the day is what do you thing the boat will run for Mph??? I'm thinking maybe mid 90's, however some belive this is going to brake into the 100's. Anyone with experience have any ideas? The boat does not have a hook either.

First of all, you adjust the height by moving the actual Stelling boxes. The drives are mounted in the same place.

I would think when its 100% dialed in, you could hit triple digits.

My boat had similar power with it's previous owner...-2 Imcos, Imco boxes, blueprinted hull...he hit 106. Can't really tell from your avatar...are you stepped or not?

Non step
