In an earlier post I described the challenges I encountered in creating a simple, rear engined trike.
My kart uses a Morgan for inspiration, so a front mounted engine actually seems more appropriate.
Where can you find any relevant info on how to achieve this?....Not very much out there in the Cyclekart, Gokart and Buggy worlds. I did eventually find a sport which gave some clues.......Thai long tail boat racing!
These guys use every thing from worked over 2 stroke moped engines to V8's. The 6.5 Hp GX type engine is also a popular class.
GX200 powered ones are also becoming more common in the USA as 'mud boats' for fishing and hunting in shallow water
So what can be learned? A long straight drive shaft is not a problem. A flexible or splined coupling at the drive end is sufficient. Bushes or bearings in the drive outer tube are used to prevent the shaft from whipping about.
A prop shaft needs a thrust bearing to resist propeller drive thrust loads. This is the point where my Cyclekart differs. There is a small thrust load produced by the torque converter drive pulley, but nothing like prop load....cool!
This is the wayward path I have chosen!
