Hi!

How much power do you need to push a 38 Wellcraft Scarab KV to 80 mph + gps? 2 x 650 HP.....?

I know its a old design, but nice to look at. A classic. And reasonable priced in Europe.

Cheeers, Toffen G

more like 750hp a side

Tizbad had one with 800s that went 83. Good luck.

I just went for a 150 miles boat trip to Ottawa with a friend that has this 1986 38 Scarab KV.
Former Miami Vice Edition repainted.
He hits 67 MPH with a 425HP TRS set up running 21 pitched 3 blades. He has about 450 Hours on it.

Hope this helps.

A friend of mine has a 1980 Wellcraft KAAMA SE with a pair SUPERCHARGED 509" engines that make about 730hp each and if his boat donesn't run 80mph it is/runs very close to 80mph. I have run along side of him in my 32' Active Thunder. His boat is made out of Kevlar and has #2 SSM and does NOT have a notch in the transom. The 509's he has have flat tappet hyd cams, bowl/pocket ported GM rectangle port heads, Holley dual 750 carbs worked over by Nickerson, Superchiller innercoolers and aftermarket GIL exhaust manifolds with dry pipes.

I think at least a pair of tall deck 540 cubic inch engines would be good engines to start with and supercharge those. I don't know what kind of budget you're on, but they're not really that much more expensive and I think you'll be better off in the long run. I love the old 377 Wellcraft/Larry Smith flat decks!----Today, they still have the look and profile of a true offshore powerboat! Have fun!

Im am building a 82 40' excalibur currently. Very similar hull. We are using ITS extension boxes and XR drives. Our horsepower should be 700ish per side. We are expecting 75-80 out of it. The biggest gain will be losing the TRS drives and transmissions. Good Luck.

GLH, any idea where this boat is today?

MrSneakAttack

it depends on what drives are on the boat
