Sobalai marine oil drain hand pump — 34060-0130 brass 3/4" swivel fitting, 1 GPM, 10.25" compact

The Sobalai 34060-0130 pump is a compact, brass-bodied hand pump that lets you extract marine engine oil through dipstick tubes quickly and with one-handed operation.

Designed for MerCruiser, OMC and many other marine engines with a 3/4" threaded male garden-hose style dipstick tube, this oil drain hand pump combines durable materials with easy setup so you can remove old oil without crawling under the engine. The unit pairs a long-life brass cylinder and oil-resistant plunger with a flexible 1/2" ID hose to move up to 1 gallon (4 L) per minute, making routine oil changes cleaner and faster on boats and other small engines.

How does the Sobalai pump connect to my engine?

Attachment is straightforward: the pump uses a 3/4" swivel hose fitting that threads onto the dipstick tube, and the included 1/2" ID drain hose snaps onto the pump’s barb. No special adapters are usually required for compatible dipstick-style tubes.

• 3/4" threaded swivel fitting matches common marine dipstick tubes.
• Barbed top accepts the provided 1/2" ID hose for a tight seal.
• Compact 10-1/4" pump fits in engine compartments for easy access.

What performance can I expect during an oil change?

The pump is hand-operated and designed for one-handed use, delivering up to approximately 1 gallon (4 liters) per minute with about 40 strokes per gallon. That flow rate lets you evacuate crankcases and gear cases rapidly without tilting the engine or removing drain plugs.

• Produces up to 1 GPM (4 LPM) output for efficient draining.
• Approximately 40 strokes required to pump one gallon of oil.
• Removable parts for flushing and cleaning after use.

What materials and maintenance features does the pump offer?

Key components are built for longevity in marine environments: a brass cylinder resists corrosion, oil-resistant plungers preserve seal life, and impact-resistant end caps withstand rough handling. The assembly disassembles easily for periodic cleaning to avoid cross-contamination between oil changes.

• Brass cylinder and brass 3/4" fitting for corrosion resistance.
• Oil-resistant plunger material to maintain suction and durability.
• Impact-resistant end caps and removable hose for cleaning.

How do I use the pump safely and correctly?

Install the drain hose and screw the swivel fitting to the dipstick tube, place the hose into a waste container, and pump until the crankcase empties. After draining, wipe fittings, stow the pump, and start the engine as recommended before refilling with fresh oil.

• Connect hose to barb, thread swivel onto dipstick tube, position waste container.
• Pump with one hand until oil flow slows; wipe fittings to avoid drips.
• Start the engine per manufacturer guidance before adding new oil.

Who is this for: The Sobalai 34060-0130 hand pump is aimed at boat owners, marine mechanics, and DIY hobbyists who perform regular oil changes on MerCruiser, OMC and similar engines with a 3/4" dipstick tube. It's also useful for small-boat rental operators and marinas that need a reliable, portable solution for quick oil evacuation without lifting or tilting engines. If you want a straightforward, durable, and serviceable pump that minimizes mess and speeds routine maintenance, this model is built for that purpose.
