Description
Already have an RTA-17, MKA-21 or similar mount already installed or previously installed? This deck plate adapter made from very strong 0.50″ thick 6061-T6 Aluminum will allow you to install an SS-7-HD or SS-9-HD mount and use those same four (4) holes in your deck and completely eliminate the need for any new holes in your deck! The adapter will add 0.50 inches of height to the mounting surface and becomes the surface that any of our SS series mounts attach to.

I had the MKA-21 mounted on my Triton T17 Crappie Pro. I did not want to drill new holes in the deck. I used the 4 holes from my MKA-21. It was a very easy installation, very quick too, I’m impressed (I even called them to let them know how great it was). I got the 9hd mount with this and my Terrova slides back 9 inches and does not hit the bow roller on the trailer anymore. These guys really know what they are talking about. I got the exact mount I needed.

2024 Tidewater 21.1 Baymax, When launching the boat, the trolling motor would hit the winch stand roller hard. Mounted on a SS-9-HD with the BMA-12, problem solved. Trolling motor head also still clears the trailer guide-on poles mounted on the rear of the trailer. Used the BMA-12 so I did not have to drill new holes in the boat from my rta-17. Best customer service around also.
