GROCO 3 Port Oil Change System w/Reversing Switch - 12V

The GROCO 3 Port Oil Change System with Reversing Switch 12V is a purpose-built marine oil circulation pump designed to streamline engine maintenance on fishing boats and cruising vessels. This 12-volt electric system uses a powerful gear pump that delivers nearly twice the flow rate of competitive marine oil change systems, enabling faster, cleaner oil servicing without the mess and labor of traditional manual methods.

The system's bronze manifold construction resists corrosion in salt-water environments—a critical feature for offshore and coastal boaters where galvanic corrosion can degrade equipment rapidly. TouchPad controls provide intuitive operation, while the reversing switch allows directional pump control for flexible system configuration. Built-in resettable overcurrent and dry-run protection guard against common operational faults, extending pump life and preventing damage during routine maintenance. The 3-port valve configuration accommodates modular expansion up to 6-port capacity, adapting to different engine layouts and future upgrades. Oil pan adapters fit all common marine engine types, eliminating guesswork during installation.

Weekend fishermen and serious offshore anglers both benefit from centralized oil circulation systems. The GROCO reduces service time between fishing runs, minimizes spills in the engine compartment, and extends engine life through more frequent, thorough oil changes. Weighing 12.6 pounds, it installs compactly beneath deck with minimal disruption to existing bilge and fuel line layouts. This system suits single and multi-engine vessels where rapid, debris-free maintenance preserves engine reliability and resale value.
