Ordered the complete upgraded cooling kit
For my bj42 worked perfect
And
Def
Runs cooler also previously
Pitched prop amd thing runs like a gorilla on roids

I have to say the 8mm cooling lines are great with the outlets and it give my proboat blackjack 42 a great look and a nice flow through the system my esc and motor stays cool on blasting runs.

Thanks for the review.

This is a great upgrade, comes with everything needed to two separate cooling lines one for the motor, and one for the ESC. The lines are thicker then stock so there’s a lot more water flow. I’m not sure what the exact temperature was before, but I can feel they are a lot cooler to the touch. Plus you get aluminum through hull fittings, and water outlets, eliminating the stock plastic outlet. I recommend taking your time when drilling the holes so you don’t make them to big! Also pay close attention to the transom through hull fittings, as there is the stock bulk head reinforced ribs inside the hull that may affect being able to screw those down all the way. There is plenty of cooling line in this kit, but you should map out where you want your lines to run before you start cutting the lines. I did one piece at a time, as I took the stock lines out to ensure I wasn’t wasting any line. All said and done, there wasn’t much excess, so take you time and everything will be nice and cool!
