Yeah, the 19. Here is all I know. I was told that there was only two ever built. When I saw it at the boatshow a long long time ago, I thought it was very cool. I was told that the boat has an unsolvable porpoise problem. It would be interesting to try to fit it, but may be that is why it did not make it past two units built.
I would expect that like almost all things Scorpion, it is loaded with issues.
Funny...they both were up here at one point. The other I know about is merc racing colours and had a 2.4 "bridgeport" on it....it was THE boat I wanted when I was 14. This one doesn't really seem to have any glaring issues other than it probably could use a transom (but it is a 1989)....and....assuming that it does not have core..ahem. The gel work is amazing given the reputation that scorpion has for build quality. The other 19 was the same in that respect...
When I recieved the boat it had a 25" 2.4L 200 and the boat didn't really have a porpoising issue...but also wasn't very fast 65 TOPS. Now with the 20" Opti AND 200+ litres of fuel behind the back seat it does!! He was running a thru-hub cleaver and now we tried James' chopper so...maybe a stern lifting prop might help (as well as burning half the fuel off).
