Sea-Dog Manual Oil Change Pump

The Sea-Dog Manual Oil Change Pump (model 502006-1) is a hand-operated pump system designed to drain oil from inboard and I/O marine engines through the dipstick tube. This tool eliminates the need for hazardous crawling under engine compartments or removing drain plugs, making routine oil service faster and cleaner on the water. The pump comes equipped with two drain tubes to accommodate various engine configurations and dipstick diameters found across different boat powerplants.

Weighing just 0.5 lbs and compact at 6 x 2 x 11 inches, this manual pump fits easily into engine compartments with limited access space—a common constraint on cruising and fishing boats. The hand-pump mechanism requires no external power source, making it reliable for remote anchorages or when shore power isn't available. The two included drain tubes provide flexibility when working with different engine bay layouts, reducing the likelihood of spills that contaminate bilge water and compromise water quality. Manual operation gives the user complete control over flow rate, preventing overflow in tight compartments.

This pump is essential for weekend anglers and liveaboard boaters who perform their own maintenance. It streamlines the oil change process on both gasoline inboard engines and inboard/outboard (I/O) stern-drive systems, reducing service time during scheduled haul-outs or routine dock-side maintenance. The tool is equally practical for owners who want to avoid professional service facility costs or maintain full control over their engine maintenance schedule while cruising extended distances.
