Re: sab motor with varable pitch prop
As HS says, you need to reverse the prop pitch to go backwards.
At least on my step dads boat, he has a engine throttle, and a pitch control throttle that are in the same control unit. Generally speaking, we put the engine at 1200 or so rpm, then work the pitch to go backwards at the speed we want to go. Seems to work reasonably well, not something I would want on my boat. I can see how rescue style boats a system like this would work really well.
