Hello, i have a small Bandit rc hull i use for the girlfriend, the boat used to have a Lehner 4200 XL but such a small hull and that motor was WAY to overpowered, radar showed 61 mph
so i needed to slow it down for her and give long run times.
I ended up buying a Turnigy 28/54 inch brushless 3700KV motor for it and a cheap 90 amp esc
the 90 amp esc was chosen because there is usually alot of part throttle driving, and some of you may know part throttle will cause more heat, so i over did the esc to allow for lots of room while driving.
because i went from a 36 MM can to a 28 MM can, i had to make my own water jacket HK was out of stock.
I have done this before and it woks well for odd sized motors and motors you just dont need to look pretty.
first i cut apart a rattle can paint can, Cleaned it out and rolled it inside out, with measurements i measured the size of the can with the O rings ( black O rings from your hardware store)
then i folded up each end at 90 Deg, then re enforced it with a piece of angle brass, i covered it with flux and used a propane torch to solder the angle brass to the paint can.
once that was done i cleaned it up a bit, then drilled holes for the bolts to go through
drilling the holes for the water to enter and exit was eazy, again small holes and brass tube ( i used 1/8th), then solder it up!
then place around motor with the rubber O rings and you have a water jacket,
I use my favorite stuff in the boat business, bellows Adhesive by Mercury.
i layed a little right where the water jacket clamps together and it created a perfect seal.
Bellows Adhesive is great stuff, its easy to remove, dries fast and is a fantastic sealant, glue, and is non conductive.
i use it for all my running hardware and all thru hull fittings.
there you have it, a not so pretty water jacket for that silly motor you have a hard time finding one for!
