Hi there Derek/Ron,
I came accross this in our local club mag, a mixer
that will proportionally slow down the inboard motor and add power to
the outboard unit, steering is as good as if you had twin sticks for
throttles will work at rest to send one motor forward and the other
in reverse allowing the boat to spin on its axis it will work with
2,3,4 or more screws (or paddles) cost? US$40 +$3.50 priority mail
(to Canada) contact @ CaptnAJ@aol.com............Dai Powell
