I am not planning to use an oil extractor on anything that I can drain it out of, but our new boat with a Mercruiser 4.3MFI requires an oil extractor to get the oil out of the engine.The one I am leaning to is the Moeller 5.0 Liter Fluid Extractor Oil Change Pump.
Moeller Marine Fluid Extractor/Oil Change Pumps
Anyone have any advice. Thanks
