A few questions on these cool little boats......
1) Does anyone have some pics of these things? Did an image search on google and came up with a pic of a black one with a wing and the factory image from the brochure.
2) How many were made? Ive read 1-2 dozen or only 4 made ... 2 racing versions & 2 production versions.

I worked for a dealer that had one.
Not sure I remember the wing?

2.3 liter pinto motor w/open, over transom header.
Was a fun boat to drive but needed a turbo.

Ran 55 as I recall. Cool little boat.

I think the regular version did, but the racing version didn't. Mine didn't it was some sort of prototype.
