Nice V20 on Ebay

[Blue_Runner]

RAP - in 1986 (I think) Evinrude/Johnson switched thier HP ratings from powerhead to prop.

At that time, a 100hp motor went down to 88hp. Extrapolating the numbers upward at a loss of 12% would make the antique 235 hp motor about a 200hp or less.

Some estimates I've found indicate as much as 25% diff between head and prop. If this were true, the antique 235 would be about a 175hp. Depending on prop and compression on this motor, and the weight of older motors, 41 mph might be reasonable.
