having trottle finding the appropriate control units and recharge

would sell me the control hardware seperately.



thanks

Google, golf cart parts

Golf carts use DC motors, solid state controls, and charging systems that
might adapt, if your interested in designing your own system.

Electric forklifts also use the same, and some can handle very high
amperage.

Batteries are the weak link in this.



they certainly are. but they should be sufficient if you only plan to
use the motor for anchoring or emergencies. i suppose in these
situations you only needs short bursts of 'reliable' power, which
electric drives are suppose to provide. this particular manufacture
claims 100% output in 2 seconds.

wouldnt be practical for prolonged operations
