I actually used to race one of these on a 22ft Velocity in A-class. As long as your not putting a ton of torque through it, it is a great drive. I put 500hp through mine at 7200rpm and 93mph.

I also bolted mine onto a friends velocity and it gained 8mph from his standard Alpha.

These are 3.5" shorter than a standard alpha and have the 2.4 liter outboard crescent gear case with low water pickup. I ran mine on the surface with a cleaver prop.

I don't know the seller, but do know these rare drives. If anyone wants to ask questions in general about these drives feel free to call me. 239-443-8233

2.5 inches shorter not 3.5
I gained 10 MPH when I bolted one onto my Glastron.
But I had 500+ HP also and could snap the drive at will.
ended up selling the boat.
My best speed was 94

Correct 2.5" shorter than a std alpha.
They came with HD upper gearsets. The shorter vertical driveshaft is NLA from merc. It had a recessed oring groove near the upper splines. When overpowered, this was a common breakage point. The cases are also NLA. Standard Alpha gears/bearings in lower.

Ran one from 08-2014 on a 383 500hp 21' Challenger. 5mph & 500rpm gain with no prop work. Member SB here is still kicking s***! with it.

My motor was a 357ci small block chevy. This drive will handle big power small cubic inch motors. Big torque/ cubic inches will snap these quickly.

$2500 is a great price ! This was the quick sale price 5-10yrs ago. Some where getting $3000 but had to wait longer to sell.
If no action here (mostly BBC I/O's and outboard boats on OSO) I'd go to the Donzi site. Should be fast sale there. Like, real fast.
These don't come up for sale much. Sometimes takes a few yrs to find one.

I heard the same !

Did the SS drives come stock on anything or was it a aftermarket merc part?
