I emailed both Lenco and Bennett asking what they recommend for surf tabs for my boat and got the follow responses back.

Lenco
All of the surf tab systems we sell are custom designs by various OEMs. They are therefore proprietary blades & controls. We are not permitted to sell most of these blades through aftermarket distribution due to this fact. If customers are creating their own surf tab set up, they are doing it without recommendations from us, as it violates the agreements we have with our OEMs. Please let us know if there is anything else we can assist you with!

Well, we offer Wakeplate systems, but we don’t specifically manufacture Surf tab systems. Of course, they are basically a trim tab system installed outboard as far as possible either in a normal trim tab installation (trim tabs positioned to deploy down into the hull surface’s water flow or tilted outboard to deploy outboard into the side wake. The later choice is normally reserved for the ski/wake boat manufacturing companies, since that can design the hull around this type of application so the vessel will run correct & true from the factory (not recommended as an aftermarket installation). One of the main issues with Surf tab systems has to do with the vertical height requirement to install the actuators so far outboard on a ski/wake boat, since these vessels normally have VERY LIMITED height to work with under the swim platforms. We combat this issue by being able to manufacture shorter overall length Classic Hydraulic Actuators, which CAN STILL have our standard 2-1/2” overall stroke length that is normal for a standard TRIM TAB SYSTEM. Also, the overall shorter length actuators allow us to install the actuators at the standard attachment point (8-5/8” back from the transom) on the trim tabs to obtain 20 to 25 degrees of trim tab deployment when installed. And one more capability we have with our Classic Hydraulic Actuators is that we can modify the overall stroke length of the actuators too. We can increase (up to 3-1/4”) or decrease (less than an 1”) per the OEM’s request, so we have quite a bit of customization capabilities to meet our clients needs.Do you have a photo of YOUR transom you can email to us, so we can see what type of mounting limitiations you are working around?
