Default 2 speed Marine transmissions

we have been working on these for a year now and they are just about ready. they were designed and built for high hp marine applications. not based off a powerglide like the other two speeds.

they bolt directly in place of a bam or huber to your bell housing, they have a much larger piston then the bam or huber to push on the clutches and more clutch plates with more line pressure.
low gear is 1.5 to 1 for ease of docking and getting on plane.
they are rated for 2500 hp with a one year warranty.

they have a bolt on flange for the back so they will work with the different size u-joint flanges.

I would imagine these would be very nice with surface drives, which have particular trouble accelerating when most of the prop is submerged on startup. The Bravo outdrives are already torque limited so the transmissions would mostly be useful for slow speed, non-full throttle operation. The V-drive people may be interested in this, too.

If you need a Guinea pig, let me know, i'd love to try them! What do they cost? Feel free to PM me.

I'm going to look at the hull this weekend.. the cummins are coming together in the next few months and we are looking at 2 speed powerglides... which are going to need a lot of work before they are hp/ torque ready for the motors...

what kind of torque rating do these have, and what is the power loss through them compared to others available and what is the PRICE?
