want to build a push systeme for kayak.

Ok i am sher you guys no about the few systems out for kayak.

like native propel and hobie fins.

i want to propel my kayak wit a systemes....that use the same princip as the hobie...a little push pedal type....and it would turn a prop in the back.

so for the back it would be a flexiable drive shaft that would eneter a hull and a prop would turn in the bottom off that kit.

so my prob is the push systems....its not a turning like a bikje ita push systems like hobie style...that would make turn a prop in the back.

any ideal if any system existe already.?
