Collection: Oil Change Systems

Changing your engine or generator oil on the water does not have to mean awkward hand pumping into a makeshift container. The products here range from simple manual pumps and 12V electric units to organized bucket kits and multi-port systems that can service several engines from a single panel. Sea-Dog covers the basics with battery-clip-powered and manual pumps suited to smaller single-engine boats. Johnson Pump and Albin Group offer gear pump kits in both 12V and 24V configurations, paired with collection buckets for a contained, mess-free job. Jabsco's flat tank changer combines a dedicated 3.5-gallon reservoir with an electric pump, while GROCO's 4-port and 6-port systems with reversing switches address larger vessels running multiple engines or generators.

Before choosing, confirm the voltage your boat's electrical system supplies, 12V or 24V, since most powered options come in both. Consider how many fluid sources you need to drain: a single-port kit works for one engine, but a GROCO multi-port system saves significant time if you maintain several. Manual pumps need no wiring and suit occasional or backup use. Gear pumps move oil faster and handle heavier viscosities better than flexible impeller types, so check your oil weight against the pump spec. All brands here are stocked as authorized dealer inventory, meaning you receive genuine products backed by full manufacturer warranties.
