You are offerding for a set of plans for snowmobileengine conversion system (redrive+motormount). A lot of ultralight, hovercraft,and airboat builders all over the world use these converted engines. A lot ofredrives exist for them.

This classical system consistsof two 6061 T6 aluminum pulleys for 5 V-belts, eccentric shaft with heavy-dutyclosed ball bearings, motormount plate and all machined parts, rubber elementsand hardware necessary for engine installation. It can be easy made at any evennot high-tech machine shop. Tested and proven. Pulley drawings are included.You can easy get any desirable reduction ratio just changing the big pulleydiameter. Standard shape Rotax-style hub allows using standard propellers. Iused these redrives ith licensed Rotax 640 as powerplants for\"Frigate\" trikes. It has been installed now with Rotax 503 on my\"Eagle\" (look my another sale for “Eagle” plans) trike. Niceflyer. Air Trikes Enterprises is selling the set of plans for this system.

f) The engine can be installed head-up or down.

g) This system can be easy adjusted by changing someinstallation dimensions to almost any project.
