Heat is typically not an issue with most electric systems, Lloyd, as long as you are not pouring too much juice to your motor. At Electric Yacht we have standards for each system and we bench test each complete system to those standards before it gets shipped for installation. Our settings serve to prevent the motor or controller from overheating. We also use a heavy anodized plate as the heat sink to mount the controller as that will always generate some heat.
No cooling systems, air or water are necessary. Just another one of the maintenance items that goes away when you convert to an electric system!

Speed is not real important to me.) On-board solar and wind generators could provide for the recharging of the batteries. (I have solar panels on-board my boat.) And an on-board generator using any fuel should provide power when the batteries are depleted.
