This model is ideal for vessels requiring high-flow raw water circulation with the convenience of electrically controlled engagement.
Electric Clutch – On-Demand Operation
The integrated 12V electric clutch allows the pump to engage only when water flow is required. This minimizes belt wear, reduces engine load, and extends pump life—making it ideal for marine air conditioning and cooling systems that cycle on and off.
