Yea, I've seen 65.3 GPS with mine. I'm making 502 HP at the flywheel, probably around 475-480 at the prop. My outdrive is too deep and I could probably get a couple more MPH with the right drive height. I don't believe the 70 MPH with twin 200s. The Seavette is a heavy boat and I believe that it would take 600+ HP to get it to run 70 MPH.

I would guess high mid 50's with that rig . . . unless the motors had some work done. 2.4L powerheads can produce 250hp + with some mods and at 363lbs each you might get into the 60's. Those motors in stock form will cut out at 5800rpm because of the idle stabilizer/spark advance module which means you'd have to be running at least 28pitch choppers to hit 70 with stock 1.87 ratio lowers.
