Double Stack NBT Marine Cruiser (18”) with 12” unit on Bow

[kzvw21]

Has anyone double stacked an NBT Marine monitor with a 12” unit on the bow of a Phoenix 21 PHX. Will it work on the factory double stack fiberglass mount plate or do I need to buy the BBT system. I plan to buy the BBT gimbal bracket at the least because I fish big water up north. Please let me know other options.
Thanks!!

I run a 16", 12" and a 10" on a boatefx triple stack over the pedal mount and it's been rock solid, not sure if I would trust that much weight on the factory mount

Thanks for the reply. I went ahead and bought the BBT mount with the BBT gimble bracket. Thanks again
