I purchased a 2011 MB Sports B52 and decided it needed a surf enhancement. I read a lot of forum threads on multiple sites. I started with a wood "Slapper" (It's an MB thing) that slid on the step and attached to the tie down eye. This worked great for the one time we used it heading into winter. Unfortunately winter daydreaming about summer made me plan out a set of powered Slappers for the spring. I used white HDPE for the Slappers themselves and Lenco fast 4.25" actuators. Even though I had seen other versions with the slappers below the step height, I felt they needed to be a little taller to be the most effective. I shaped them with an elliptical curve to match the back end of my boat at the top. I didn't want a square cutting board hanging on my boat. After getting the nerve to drill holes under the waterline I mounted the boards and actuators.
I know the WL controller is the best control option available but I couldn't see the need for the GPS option or the high cost of the controller. Being a control freak, pretty savvy with relays, timers and wiring, I came up with my own controller of the slappers. It was complicated to come up with something that would deploy the actuators with a momentary signal and give a light that it was deployed, but after a few sleepless nights I figured it out. In the end I hit one button to deploy my goofy actuator and pull my rider. While driving I can switch sides by just pushing the opposite button. The deployed acutator retracts and the other actuator deploys. The lights on the switches follows whichever gate is deployed. When the rider goes down, I press the Wipeout button and any deployed actuator retracts and I drive back to the rider without any steering issues. It really is a simple set of controls that is very intuitive and doesn't need complicated programming to adjust.
