ok ok you found me.
Yes I have the small block 200 etecs on my 23.They are mounted on an Armstrong Bracket.
Depending on the prop I run here are my results.
21 pitch Vipers
Top speed 64mph 1.6 mpg 5900 RPM
Best cruise 34 mph avg 2.2 mpg
19 pitch rev 4
Top speed 56 mph avg 1.5 mpg 5850 RPM
Best Cruise 31 mph Avg 2.1 mpg
These are with a full tank, 28 gal of water. 4 people and ice.
Runs were done with wind from left to right at 5 knots. Slight chop on the Banana River.
It's been a while since I did these test. So i may be a little off.
Before ethenol fuel my numbers were much better.
