I’m back, we’ll never really left
Not sure really. This one will be the first marine brushless esc I've used. If you use a car one you may need to re configure it as most car ESC's are set up as F/B/R or just F/B, obviously with a boat brakes are no real use and no reverse is even worse. I imagine most Marine brushless esc's are unsensored as they need to be waterproof. In cars the unsensored ones can "Cog" or "Stutter" at low speeds not sure how this would affect a boat. Mainly I would guess it may cause a less than smooth transition from forward to reverse.
