GSA Surf Controller

The surf controller powered by E61 is designed to where you will have 3 buttons and 1 dial.   So you will have surf left, surf right, and reset.  The dial will allow you to fine tune your wave to either make it skim style or surf style depending on your preference.  This controller can be placed in your boat wherever is most convenient for you.

Controller Information

This key shows the different functions of the controller and how they are used with GSA.

Swim Platform Brackets (Triangle on Top) - $599.99

Depending on the boat, you might need swim platform brackets to raise your swim platform so that it does not interfere with the wake.


Note: All Mastercraft model boats will need these swim platform brackets.

Tabs available

GSA tabs are now polished stainless on all systems besides Xstar tabs.  These look absolutely amazing!  Xstar tabs are made from clear, anodized aluminum.  Here you can see the difference.  The pic on the left is the Xstar tab (longer design) and the right tab is for all other model boats.
