Getting this engine for our sailboat dinghy:

We have tried wing foil surfing and are hooked. The kids would live to foil behind the dinghy using a cord to hold. Our current 6 hp gasoline outboard isn’t strong enough.
Here’s a video to illustrate:
The battery from Great White above looks sturdy.
After having watched:
I would like to build my own waterproof battery for the 10 hp electric outboard. Cheaper. Can I make that server rack battery water proof? Encase it somehow? Or is it better to get a stainless box, build everything from scratch with cells, BMS etc?
Got Daly BMS aboard the sailboat and I don’t like it, it “falls asleep” etc,
At home (the villa) we have 16 kWh battery bank with 123SmartBMS. There’s a circuit board on each cell. Works good and powerful! I can draw +10 kW three phase from the bank, in and out. Should I go for 123SmartBMS instead for the portable battery?
There are two approaches for the battery.
1. Portable
2. Less portable, put it inside a locked compartment in the bow of the dinghy. We need to swap dinghy then to something like Highfield:
Both need to be IP65 rated.
Perhaps start with portable. We have a 7OC dinghy today. Perhaps build 2 x 50 Ah batteries rather than a 100 Ah?
When in a marina the battery can easily be charged using shore power.
When out cruising without electricity we have a DIY 5.1 kWh (12v 400 Ah) LiFePO4 battery I built aboard the sailboat. And inverter. + 310 W solar panel. Can also start engine to get electricity.
Could use that to charge the dinghy battery. There will be two conversions:
12v DC -> 230v AC -> 48v DC
Could also build a 12v DC -> 48v DC step-up solution. One conversion less.
The dinghy is often parked in a dinghy dock, or lying beside the boat. I would like to buy a 100-200W foldable solar panel with large eyelets in each corner. You can run a wire through these and lock it together with the dinghy and the outboard.
Need to find a suitable 48v portable MPPT for that.
