Re: 1973 23 SEACRAFT rePOWER
I think Brian is close. The tower will slow you more than you might think, though. I'd estimate 34-35 knots loaded, maybe 37-38 running light.
My old '74 Tsunami with an '88/02 225 Johnrude and a clean hull ran about 29-30 kts, and another Sceptre around here with a 250 Mercury Opti and CSC Slickote bottom paint was only running about 35-36 kts WOT, according to the owner.
