Whatever, everything above still applies, except throttle will be for/rev motion & it'll be rudder for steering, so rudder/gear or aux? (I'd put it on gear myself). You'll need to put a speed control on your pump, can't work without it. And if you do use gear switch, the values for throw are -100 on one side of switch & +100 on other side. Once you figure out which side of gear switch makes pump pressure (pump turning correct rotation), the side of the switch that should be off needs EPA set to 0 so pump turns off.
