Marine ESCs & Boat Speed Controllers

Part of our Speed Controllers range, our Marine ESCs deliver reliable power management for RC boats of all sizes. From fast electrics to scale cruisers, you’ll find waterproof, water-cooled options from Hobbywing, ZTW, Dynamite and Spektrum, in both brushed and brushless variants. Choose the right unit by continuous/peak current rating, LiPo cell count (2S–6S+), and BEC output to suit your servo and receiver needs. Marine-tuned firmware provides smooth throttle response, reverse (where permitted), low-voltage cut-off and thermal protection. Many controllers offer timing and punch adjustments via a programming card or the transmitter, while Spektrum Smart models can feed live voltage, current and temperature telemetry to compatible radios.

For a smooth install, check case size, cooling jacket and water pickup routing, connector type (e.g. 4/5.5/6.5 mm bullets, XT60/XT90) and wire lengths. We also stock spares and programming cards to make setup straightforward.

With large stocks backed by friendly, knowledgeable support, Wheelspin Models makes it easy to choose the right marine speed controller. Enjoy fast UK shipping with next-day delivery options available, so you can get back on the water sooner.
