The Oil Change Pump is the same high quality pump used in the Jabsco multi-engine Oil Change System. The powerful pump can change oil in a typical V-8 engine in just minutes. The pump is designed to be installed near a vessel's engine and permanently plumbed to the engine's oil pan. The pump can be used to remove old oil from the engine, then with the integral reversing switch, the flow direction can be changed to pump a measured amount of new oil back into the engine. The connection to the engine should be controlled by the 3/8" ball valve (provided) to guard against accidental oil discharge.Pump Body: BronzePort Size: 3/8" NPTImpeller: NitrileShaft Seal: Buna Lip TypeMotor: Reversible Permanent Magnet DC with Integral Reversing Switch, CE and EMC Compliant.
