Small Craft
Small craft used for pleasure or work can be found in nearly any lake, bay, sound or inlet. HOTSTART heating systems can be installed on ferries, personal craft, fishing vessels and more. Heating the engine while docked eliminates the need for wasteful and harmful idling while keeping the engine ready to accept full power when it's time to head out on the water.
