Initial stage of GSA install on 2013 Enzo SV 230+. I was  going to wait until things were a little farther along, but I ran into a snag and was a bit delayed so I  figured I would start to post.  It sounds like there a couple other Enzo owners out there who are thinking of installing. Thanks to MrWick for his thread on the supreme install. I will try not to duplicate too much, but it seems that there are some unique differences based on my transom shape.  I’ve watched all the installation videos and number of times and would agree that they are really good. Keep in mind I am not mechanically inclined so I’m going slow and asking lots of questions to Ryan at GSA. Support has been awesome.

I decided to go with the GSA system after reading numerous posts including synergytogo from last summer.  I bought my Enzo last summer coming off 8 seasons on an avy.  I absolutely love the wave listed. I experimented with the suck gate and enjoyed a that even more. I was intrigued at the ability to do transfers and the technology from GSA.  Picked the system up on Black Friday. 

 First things first. Tab mounting is complicated by the curve or radius on the back of the transom as it moves out to the side of the boat. There is also a bulge where the surf platform mounting bracket secures to the hull.  A little difficult to tell in the pictures.

 Ryan recommended modifying the tab hinge pictured above. He stated only six holes were necessary. We could cut a hole off the side of the bracket closest to the middle of the boat. He recommended going straight down and eliminating a hole on the boat side and tab side of the hinge

 This was a much better fit. It’s still was not completely flush on either end but within the 1/4 inch tolerance. The hinge adequately flexes during installation so that a spacer is not needed between the hinge and the transom. Otherwise the step went according to the  installation videos on the GSA website.

 Sorry the pictures are a little out of order but you get the idea. The bottom of the hinge is essentially level with the bottom of the transom during the mount. The mounting screws go into the  false bottom of the hull. Only the very inside screw is visible from inside the engine compartment.

 I was preparing to mount the actuators this weekend. Unfortunately there is a ridge the travels across the back of the transom right in the area for the actuator upper mounting bracket. After I spoke to Ryan, he indicated there is a spacer that I should use as a shim for the upper mounting bracket. I will be receiving that this week.  Otherwise I could not find a placement for the actuator that gave the desired displacement of the tab and tucked up adequately underneath the swim platform.

 I will post more as I progress this week. Certainly if anyone has experience or thoughts would love to hear them. Especially regarding placement of the GPS unit, control placement at the helm, any issues with wiring, etc

So glad you are posting this, back of my 14 SV244 looks the same as in your pics and I was literally measuring that late last night wondering how wide that hinge was and if it would fit. Don't know if mine is slightly wider than yours or not, but all great info to know since I will basically be doing the same thing. Thanks again for posting the pics/info.

My plan for controler....was going to be somewhere near the throttle since on my boat, you can access behind that panel fairly easy and would be able to fish the wire up there by running behind the side panel so everything would be hidden. Also would be located in area where it would not get bumped by mistake. Do you still need to mount GPS unit if boat already has one....or can you plug into existing GPS?

Cant wait to hear what you think of the GSA wave vs suck gate wave since that has been my biggest hesitation. Love my suck gate wave.....super clean, big, perfect formation with lots of push all the way past white water. I assumed that GSA would just add ability to do transfers along with ease and convenience, but there is a pretty long GSA thread on MC forum that goes back like 4yrs thru today.... and they say it had more push than suck gate cause of how the water comes off the tab. Very interested in if this is a fact or not on our deep V hull boats since MC hulls are not as deep as our boats and shaped differently.

Awesome info....thank you!!

I looked around a bunch in the helm. I think I like this spot the best. I don’t like it in front of throttle and it’s a bit awkward to reach it behind the throttle

Not sure about your GPS question. I don’t have one. PP is paddlewheel. Instructions say just mount upright. It can be under the dash. There’s a little shelf for the instrument cluster I was looking at

Great job Bomoseen!  You have had a few more challenges than I did on my 226 but looks like you have worked through them pretty well.  Placement for your control is perfect because it keeps it away from the shifter cables!   The gps antenna has a magnet on it so I just found a bracket under the dash and stuck it on top!  Keep us posted on your progress!

Got the plastic to fab the spacers this week. Optimal actuator mounting bracket placement according to GSA is 1/1.5 inches above tab hinge. This means I mount the top screw of the bracket above the “ridge” in my transom and make a spacer for the bottom 2/3 of the bracket that hangs over.

I don’t have adequate tools so a friend ripped the plastic for me on his table saw. My jigsaw didn’t work. Friction heats the plastic and it all coagulates so the jigsaw becomes useless. I took the ripped plastic and used his oscillating saw to cut the outline of actuator mounting bracket. Mucho better. Then used my Dremel with sanding head to finish the shape which worked great (better than palm sander.)

Drilled top hole after double checking tab displacement and angles. Put a temporary screw to hold bracket in place. Then drilled holes in plastic spacer. Finally able to mark and drill bottom holes in bracket.

Chamfered the holes, loaded the bracket, holes, and both sides of spacer with 5200 fast cure. Set screws and cleaned up the mess with acetone.

My actuator wire needs to run into the transom away from the mounting bracket to avoid the false floor or quick fill. That’s why it’s not running through the actuator. Just like MrWick’s Supreme install. I’ll tackle that after I mount the other side.

Looking really good! Glad to know when I get GSA I will need those pieces and be ready to do the same work you are. Nice looking job

Thanks for the words of encouragement!!

you know I honestly thought the hinge issue would be the biggest hurdle; the spacers took some time but obviously the right tools are a huge help. I was surprised by how much I did NOT like drilling with the hole saws in the upholstery under the throttle. The 5/8 bit was unnecessary on the face plate for the potentiometer IMO. 

Anyway, ran the wires on starboard side. Our helm is nice to work in behind the throttle, east to get to...

The instructions talked about being careful hooking up the potentiometer, that it only went one way and not to force it. Hope this is correct

Need to find a power source and a ground. The wire loops look huge compared to what I found. Assuming this is run off the Perko but not sure how to confirm. Any advice on hooking to power is appreciated. Me and electrical stuff are not best friends

Overall feel like I made good progress today. Couple questions for those who have done the install: 

my actuator wires enter away from the upper mounting bracket. I’m assuming just bead some silicone on the inside and outside of the hull and call it watertight?

once the power supply is hooked up, looks like the lone deutsch there connects to the plug on the actuator cable hookup?

does it matter how you connect the two cable terminals to the black box controller?

Out of curiosity, why is there a GPS on this thing?

There should be a common ground block which looks like you found in this pic.

 

There should be a common key switch block under there somewhere as well where you can steal power from.  If you have a open accessory switch you can use it for power as too.  That is what I wanted to do but I am using mine for other accessories.  I am just using the key switch at this point.

      Just read your message regarding restoring your Barefoot Falcon.  I have a 1991 Barefoot Falcon with exact same floor issues.  I also had to replaced the stringers and am in the process of replacing the floor.  My question is regarding the need to replace the foam.  Like you I have several hundred pounds of saturated foam removed and I am not certain to replace it or leave it without foam.  Do you are anyone know if the foam is necessary for any structural support, or is it just for sound and flotation?

      Actually it has me thinking of adding something between the seat and fiberglass riser. It may even allow it to rotate?  Hmmmm

      I have been told you are the expert in setting up the S238 for a great wave. We have a 2106 s238 with the surf package, our dealer told us to fill up the boat and then use the tabs, but we have figured out the more tab we put in it the less push the wave has.
      How do we best set it up for the best wave with push? We surf regular, our friend surfs goofy and her side seems to always be great, but the regular side not so much.
      Would love to have your set up and any tips you could give. Thanks so much
