"I don't think you understand, if you are going to make a custom set up, you can focus on the specs you want, not exactly what the other product provides. If you are just dropping the bait, you can stick it on a multirotor and drop it, you…"
"Hello Ben, and thank you for your answer!
Regarding bait , i need to carry the bait and hook 500 meters inside sea, release this, and boat back to coast. First i will do this manually with RC, an later i'm thinking in to use px4 and…"
Are brushless more efficient and powerful? Are you restricted to running a certain voltage with brushed motors? Curious because I have very little experience with brushed motors.

Here is a link to a Vbox hull that is 46" long in which I installed a 3hp brushless motor and ESC to replace the 26cc gas engine.
Brushless motors of the size that I used will require at least 5S LiPo batteries.
"how much weight are you towing, do you want it to suspend the bait and have a quick release when a fish takes it, what is your controlling device you want to use, what is your budges if it's not $60,000? It basically sounds like you want…"
You can buy Traxxas aluminum cooling pipe kits for 540/550 brushed motors off of eBay.
Also, there are aluminum block heat exchangers available on-line for cooling the ESCs.
I used air cooled waterproof ESCs and mounted them above board in…"
"Water cooled brushless motors would be a good start. It will be a bit of work. I think when you refer to needing more speed you mean more power. That hull is going to just push a lot of water at speeds over 1.5m/s. Mine will…"
