Hey MAC, if I were you, I’d buy this alu cooling block for the VESC 75/300! It is the perfect size and you won’t have to worry about it leaking. For 35$, it is so worth it. I have it on my setup and it does the job perfectly! I even run it without a waterpump and the flow is more than enough! My vesc temp never goes above 52C in warm Florida water and continuous riding (1hr+)
