E-cowlboy 34060-0130 Premium Brass Marine Engine Oil Pump
This brass oil pump is designed for fast drainage and broad compatibility with OMC/Mercruiser dipstick tubes and similar marine engines. It drains up to 1 gallon per minute, making it a strong choice for quick oil changes. Best for boat owners who want a robust, corrosion-resistant pump with straightforward setup. Limitations include a recommended temperature cap of 140°F (60°C) for safe operation.
Jabsco Engine Oil Changer Oil Drain Pump
Jabsco’s unit screws onto a threaded 3/4″ garden hose fitting on the dipstick tube, delivering up to 1 GPM (4 LPM). A compact 2′ drain hose is included for quick transfer. Best for owners seeking a simple, plug-and-pump experience without extra accessories. Better for single-engine setups; ensure hose routing suits your vessel’s layout.
Amarine Made Oil Pump, 12V 60W
Amarine Made offers a portable 12V oil pump capable of 0.8–1.0 LPM with a 60W motor. It’s well-suited for use anywhere, including boats, cars, and small equipment. Choose this for a flexible, battery-powered option. Caution: not designed for gasoline or flammable liquids; ensure your oil is within the recommended operating range and temperature.
Ulreon 34060-0130 Marine Engine Oil Drain Hand Pump
Ulreon’s brass pump fits OMC and Mercruiser engines with a 3/4″ dipstick tube thread. It delivers up to 1 gallon per minute and includes a 2′ drain hose. Best for universal marine use and straightforward hand operation. Limitation: guidance emphasizes correct hose direction and secure connections to avoid leaks during pumping.
Deckaura 34060-0130 Marine Engine Oil Drain Hand Pump
Deckaura provides a brass oil drain hand pump with universal compatibility for OMC and Mercruiser engines, offering up to 1 GPM output. Best for brass-focused durability and consistent performance. A potential limitation is ensuring the dipstick tube’s 3/4″ thread matches your engine model exactly.
Buying Guide
- Compatibility: Confirm dipstick tube thread size and engine model compatibility (3/4″ threaded male garden hose fitting is common). Choose a pump that explicitly lists OMC/Mercruiser compatibility if you own those engines.
- Flow Rate: A pump delivering 1 gallon per minute speeds up oil changes. For larger engines or frequent maintenance, higher flow is advantageous.
- Construction: Brass pumps resist corrosion in marine environments; stainless steel variants are alternatives. Look for corrosion-resistant seals to minimize leaks.
- Ease of Use: Hand pumps should be straightforward to operate one-handed. Electric or battery-powered options offer portability but require power sources.
- Setup and Accessories: Some models include hoses, fittings, and swivels. Verify what’s included to avoid additional purchases.
- Safety and Limits: Respect temperature recommendations (e.g., 140°F/60°C) and avoid pumping gasoline or flammable liquids with oil pumps.

Most pumps in this category deliver about 1 gallon per minute (4 liters per minute), with some variations depending on the model and engine design.
- Can I use these pumps for bilge pumping as well?
Some models are suitable for bilge pumping, but always follow the manufacturer’s guidelines and ensure the pump materials are compatible with bilge liquids.
- Are brass pumps more durable for marine use?
Brass pumps offer corrosion resistance and longevity in marine environments, making them a common choice for durable performance.
