Would like to see it run..one day.

The twin Smash Shark first

Since your going to run it in a boat why not get one with water cooling and one that will work with your surface radio.

My Spectrum is a surface radio, when the esc is set correctly no problem.

It has nothing to do with the ESC being “set correctly”. It is all about how you set the transmitter, and not all transmitters can be so adjusted. I have used aircraft controllers in boats by adding water cooling, or in low-amp-draw boats without water cooling. But Spektrum and Futaba transmitters can be adjusted so the air controllers will work. Good luck.
