I think it is 1.36... If I hit 4500 rpm then it sounds like a drop from 28's to 24's would get me to 5500 rpm at most. Perhaps I need a little more drop in pitch like a 23 ?
The previous owner specifically warned me that if I used too high of gearing it would put an unacceptable strain on the motors and I could damage them - bend a rod, etc., that I needed to properly gear it for the elevation at Tahoe. This is where Brett of BBlades comes in.

BBlades also has a test program for props.
Also, lugging the engine at too low of a WOT rpm caused by too big of props is hard on the engine and can cause detonation.

Try a set of stock 24's and then go from there. BBlades can lab them to gain more rpm, but he will most likely need a closer baseline than the 28's will provide.
