The belt-drive configuration could eliminate both sets of 90 degree

Regrettably my website needs some updating, but I thought I might excerpt this paragraph from the 'Power Propulsion' section <http://www.runningtideyachts.com/power/> "Other than direct straight-shaft drive of propellers, most marine drives today involve some sort of 90 degree arrangement; ie, sail drives, stern outdrives, outboards, etc. The 90 degree gear set (and there are usually two sets) is the potential weak link in the system. All the power is being transferred over a very physical small contact area between two bevel gears. This contact patch can be nothing more than a thin line on the opposing two teeth! Special hardened gears and maintaining close-fit tolerances permit the horsepowers of today. But when it comes to diesel engines, the situation gets worst. The diesel is by its nature a much more torque'y beast. Gears to handle an even modest horsepower diesel are extra hard pressed. Teeth can break or get worn so quickly as to loose all tolerance. The belt-drive configuration could eliminate both sets of 90 degree gears. And if desired the drive system might be rotatable about the shaft opposite the prop shaft end (the prop could be rotated out of the water when not in use)." In this application I sought to utilize kevlar belts as a drive medium. Only a short while ago a company called PYI came out with a 'morris chain' version of a belt drive. They have most recently announced that they will discontinue production for various reasons. I had written them a letter expressing a desire to take over their production of this product. They have yet to reply. Brian Eiland beiland@usa.net www.RunningTideYachts.com distinctive expedition yachts
