I had a Sceptre with 140 Evinrudes, could not plane on one engine, no bracket. Made alot of noise but just could not make the curve.

I'd love to see the torque curve for the 115 that will plane a 23 from offset to one side. As for planing from the middle. I've rigged more than one 23 CC with a single 140 Evinrude back in the early 80's. As I recall, we had them propped with 15" pitch props, and they had a top end of about 25 or 26 mph.

I think you could probably get a single 140/150 to plane the hull if you had the right prop to switch out when needed.

I must have very strong motors. With 60 gallons of fuel on board I can hit 40.5kts., yes kts. I will demo this boat planing on one motor at Longpoint. I will also invite 10 fellow seacrafters to join me on the boat at longpoint so you can see how well she rides with a big load. I run 24" stainless props and she can hit 5950+rpm's at wot.
Longpoint is now only 40 days away.

Brian,

Do you mean KNOTS or Kilometers per hour?

You probably do get an extra couple of miles per hour by not having a big fiberlass t-top.
