Just a follow up, so far the Garmin Reactor with Smartpump has been absolutely fantastic. Eliminates the snake wake and really makes the boat allot more enjoyable while underway. I added the rudder sensor and remote control as well. The remote is great, pretty much eliminates need for 2nd head unit (which would be for upper helm) and is 1/3 the price. Allot of fun to steer a 42 year old boat by remote control. It was a big f'ing job to install - solid 25 man hours and fair amount of odds and ends (50+ various NPT fittings, Parker steering hoses, flare tools, Hynautic steering fluid, #8 wire runs, new circuit breaker, NMEA 2000 network install, etc, etc).
