The biggest mistake a new FE boater can make when getting in to RC Electric Boats is choosing a power combination that is not properly matched. Now this is true for both modifying a Ready to Run hull or building a boat from scratch. In most cases this leads to excessive heat with in the system. Heat is electronics worst enemy, too much will certainly destroy any electrical component.

Over the last several years, the most difficult decision in choosing brushless power is KV selection. Please read through the Motor section to understand how this is done.
