3m 4200 or 5200 marine adhesive (quickdry recommended)

​6 Lenco #14 self tapping stainless steel screws

3/16” drill bit (lenco actuator mount)

½” wrench/socket

7/16” Wrench/Socket

Angle finder ap or device

12v power supply or tige clear in dealer demo mode (Dealer settings screen, 9191 to enter) 

24 1/4"-20 stainless button head bolts and nylock nuts (5/8" length)

Long 3/8" bolt and locknut to attach actuator to lower mount. 

Carefully unscrew self tapping screws by hand. Inspect the hull for any water damage or delamination. If there's issues new holes may need to be drilled. 

Cut the blank mcmaster piano hinge into two sections as wide as the highroller tab (~16") or your desired width to span original hem holes in hull. Once cut tack weld one end of the pin to the hinge so it cant fall out.

Copy hole pattern from original Tige tab mounting bracket onto one leaf of the blank mcmaster piano hinge. Make sure to position holes to leave at least 1/8 inch of space from bottom running edge to the bottom edge of the hinge. Copy the tab mounting holes onto the other leaf. Use a sharp drill bit and go slow.

Install new hinges into the existing holes on the transom using 3M quick dry 5200 and existing self tapping screws (or replace with new ones). Attach Highroller tab to hinge. Watch this video for reference before you start to mount your actuator tab: https://www.youtube.com/watch?v=wzNtDUj6CF8

Connect your surf tab to the hinge and then your actuator to the upper mounting bracket and the lower bracket on the hinge. Using 12v power supply or your Tige clear screen in dealer demo mode make sure the actuator is in its fully retracted position. Place the upper actuator bracket against the boat and position it so that the tab is retracted as far up to your swim platform as possible without hitting it. Mark the location of the actuator bracket on your hull by tracing around it. It must be aligned square to the hinge and usually falls about ½ " above the top edge of the hinge. Record the retraction you achieve; you should aim for at least 18 degrees upwards of your hull level zero out so the diverter fin wont affect the surf side wave.  

Extend the actuator all the way using your tige surf demo mode found in dealer settings (access code is 9191) and check the tab angle relative to the hull level using an angle finder. Aim for 15 degrees of deployment below hull level zero out, anywhere from 10-15 is acceptable. If you need more deployment move the mount lower on the transom and/or try different mounting holes on the tab. This part may take some trial and error to dial in.

Once you have tested the range in both directions using demo mode, trace around the outside of the mount bracket. We recommend using the lento mounts (https://www.amazon.com/dp/B000BAZTZU?ref=ppx_yo2ov_dt_b_fed_asin_title if you dont have a non swivel version. and drill your mounting holes in the boat using the reverse-forward drill technique. Use a 3/16" drill bit for the Lenco self-tapping screws. The bottom of the bracket is typically ½  above the top of the hinge. DO NOT DRILL THE CENTER HOLE for the lenco actuator wire, you can just feed more of it out from the original location so it will reach.

Using the dealer demo mode test the full cycle of surf positions and record the deployment angles relative to e to the hull to help with tuning later. 

​Get the clinometer ap and use that to help tune your boat. Most boats will need about 8.5-10 degrees of pitch (bow rise angle) and 3+ degrees of roll (list towards surf wave). If the wave is washy you likely have too little list, empty offside ballast in small increments or move additional weight to surf side. If wave is too short in length put more weight in the bow or adjust centre plate.

Note: There is no replacement for displacement. The more weight you can run the better as long as it can safely be done.
