When routine inboard oil changes involve more than one engine or service point, a centralized reversible pump system can help organize the job. The Reverso GP-704 Heavy Duty Oil Change System is a 12V DC electric marine multi-valve oil change system with four brass shut-off ball valves, designed for routine inboard maintenance involving twin main engines and two auxiliary generators.

It is intended for crankcase engine oil, marine transmission fluid, and heavy gear lubricants, with a powder-coated aluminum base and oil-resistant nitrile impeller/gears for marine service use.
