I have a 2000 model H2X with the 454mag 385hp it is a sweet engine all forged parts inside, something the other two engines you talked about don't have. {I believe the scorpion, and the HO
have forged parts, correct me guys}I have read were the 496
375hp motor runs within 1 to 2 mph of the 454 385hp, and the 320 hp is a little slower than that{another 1 or 2 mph} if you want a supercharger later on get the 454 mag.

Thanks for the replys

Why do you think this boat has not sold in the past two model years.

Thats 454mag is a great motor, I wish my 232 had one in it.. I only have the regular 454 300hp and my boat does between 58 and 61, depending on passengers and fuel.. save yourself 10 grand and get the 2000.

There are many reasons why that boat may never have been titled. IT could have been used by the dealer as a demo, by the dealer as a demo boat and personal ride. Dealers can use boats and not title them. Wouldn't hurt to ask ???. good luck...
