Ok, here's the deal... I have only seen one (1) photo of a Gheenoe Classic with a Vanguard V-Twin AirDrive system, supposedly installed by “Mosquito Power”... It has since been removed from the internet. Anyway, I am beginning the process of creating my own AirDrive Gheenoe... I have a "HiSider" (15.4” x nearly 4’ at widest point) and it is rated for a 10 HP outboard, which I currently have on it. On order, I have a military surplus Teledyne-Continental (new, in the original crate) 4-cylinder 32" displacement (approximately 525 CC), which I will set up to accept prop & hub. The engine was "dumbed-down" by the Military to 6hp for their purposes of powering generators, ground equipment, etc. From my research, the engine has a restrictor plate/governor, which once bypassed, produces 20+ hp. I researched and found a fellow who set-up the same engine in an ultralight glider which performed great @ 2800 RPM (Prop RPM). Anyway, I know that the Gheenoe is an unbelievably stable craft and generally flat-bottomed at its widest point... I can currently hard-turn this boat 90 degrees with my Mercury 9.8 hp at about 23 MPH without incident – the boat banks out of the water at a 45 degree angle, mainly because of the lower unit in the water, otherwise would slide well (with nothing protruding into water). Also, I can walk down one gunwale without the boat overturning. The boat can be powered/turned at 3/4 throttle with the outboard while I am standing, indicating that I can work with the "center of gravity" of the proposed AirDrive. I will build the AirDrive regardless, but am open to any comments or suggestions. Thank you.
