Hydra 120 BL ESC with Reverse

Here's the Castle Creation's HYDRA™ line of water-cooled brushless speed controls for marine applications.

The Hydras use FETS that offer 50% less resistance than those used in the original Castle Barracudas – that means cooler controllers at unbelievable power levels. Castle has also added water-cooling heat sinks to take these controllers to even more incredible power levels.

HYDRA 120 packs a lot of punch. Castle uses 10 gauge cables on them to handle the amps!
