here's what it says on the novak site.
ALWAYS USE ESC HEAT SINKS
Heat sinks are factory-installed on your HV-Maxx ESC and MUST be
used for maximum cooling and performance––Never allow separate
heat sinks to touch each other or any exposed metal or conductive
surface, as this will cause a short circuit & damage ESC.
the individual fins don't matter but if two banks of the sinks touch it's bad
I must say that this is pretty stupid on Traxxes's part. That means if the boat takes on enough water to come in contact with the esc then it will short out. I personally think that all boat esc's should be water proof. DUH
