I Need A Shrink !

[cdavisdb]

Did a little internet research and found only two gear ratios for a 290 duoprop, 1.95 (part no 872885) and 2.3 (part no 872886) Mine must have been a 1.95.

I'm real curious how yours will run with a carbed engine and aluminum props, as a comparison to mine. When you get it in the water, speed at various rpm, wot, and fuel economy would be much appreciated.
