Gday Brad,
Me again, from Waters. Welcome firstly & thanks for reading the forum.
No probs with dunking brushless outboard into the water.
Not sure on ul1 motor, but I am sure others here have used it.
I use a 100amp in
one of the tunnies, but it is HV esc. What is your make of esc?
TS2, like you have heard, will handle good power setup. Try 4s 5000MaH lipo, 30c min. Don't go over 5s, ask me!
I do not use 215, but Octura 438, 440, 442 & abc 40x53.
Not sure on the painting of a TS2 unless your a pro & know what your doing?
I don't think 2 x 3s in parallel 2200 would shift ya tunnie to great speed.
Tunnel rats from the US/Canada here will help & guide you.
Pete Repeat.
