Yeah i like this too Pipe lol The old 2 thursty 5 motor have a new name lol. But notice in this pic the motor is on a plate on the transom signs of a bad transom :-/ And he has put a midsection extention on the motor. It's actually a 20 inch motor with the 5 inch ext. Humm :-/ plus the plate on the transom that's a bad sign.

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. Blue's $.02

Good point(s), Blue. Age, compression loss, take their toll on an engine. The 155 hp Johnson I had would push the ol' Pipe Dream along at 38 mph back in the day. But in later years that went down to 32-33 mph, all other things being pretty equal.
Skool, I don't much care for that extension, either. And that plate goes away down the transom, often not a good sign. However, it isn't uncommon to see yards use a plate when re-powering, just to be on the safe side, even if the transom checks out. |

Thats true, I've seen guys put them on newer boats too. Supposedly preventing problems especially if powered on the heavy side of the ratings :-/

Nice V-20, but way out of my buget. Maybe I can cut his grass for the next ten years to lower the price. ;D

All:
I can answer the 2 thirsty 5 questions from the voice of experience. 41 is just about right with a 14.5X19 pitch prop with the motor turning 5200 - 5300. The extension can be easily removed ( I have one installed on my unit) and can be reused on a number of lower units, making a 20 a 25 " shaft. They work quite well but are rather pricey. Why he's running the motor so jacked up I can't even guess. But if he was smart he's pull the extension and sell it on ebay seperately, lower the motor to where it should be and make himself a couple of bucks in the process. Kamikaze
