   Maybe you should run the cooling to your esc first to keep it cooler.

   Can you turn the waterjacket on the motor a quarter turn so cooling would be on the side of motor?

   A rigger of size has only limited size inside the tub. You should give the watercooling jacket of the motor a little spin to finetune on the watercooling tubing. No springs needed. You save weight on the spring, should have saved weight on the motor instead. Then the motor-angle is far from ideal. Using a flex-cable with proper bend would have enabled you to move motor to the rear.

   love the pig rig, might make something simular but use a couple of drone motors and cut down props .

   Secret. If you run a high (enough) amp rated ESC and don't over prop you don't need to water cool to save weight. I find that to be more effective than actual water cooling which does cause slight drag.

   Another secret, if you have to water cool, you don't need larger water opening in the rudder to get better cooling just causes more drag. A small diameter builds more pressure causing a higher flow of water which is what is desired.

   Also water cooling ALWAYS goes to ESC first then the motor like others mentioned.

   I think is still to heavy on the prop, you should try to put a little sponson on the back (left) to let run the motor higher.
   This is the reason why everything is still too warm … with 4s should fly …

   in my practice, I rotate the cooling water jacket about 15-20degrees towards the side of the boat. In that case, it won't touch the top hatch. I also have separate cooling suction; one for the motor and one for the ESC. Make your boat a little longer so that the boat won't jump and bounce. what is your prop and motor size by the way?

   See im not huge into RC boats at all, but I like watching people mod or even build RC boats, I find it interesting, but I would rather stick with Short course trucks and Monster trucks, I just like throwing dirt and its just more convenient for me.

    Could have used 90 deg elbows that has tube coming out the side instead of from top.

    Never use oil on a tube, the oil never dissipates and will compromise the tube's friction-fit.
    Use water to lube👍🏼
