Re: Speed control
I've heard nothing but high praise for perfect pass. I've never installed it myself, but I understand the installation is not that difficult. One concern I would have with Mercruiser's SmartTow is that it is an RPM based control. I'm not sure that this would manage the varying changes of force a boarder or skier would exert against the boat as they cut back & forth. If anyone has experience with Smarttow, please add your comments.
PerfectPass is a speed-based system that makes many tiny corrections to the throttle based on the speed of the water passing over your hull. This system adjusts immediately to whatever force the skier is exerting on the boat. I'm not sure if an RPM based system would react as quickly.
