The LiquiVac Oil Change System for Large Projects and Large Engines makes boat oil changes quick, clean and easy. This is especially true with hard to access drain plugs found in inbourd engines and outboard engines. The LiquiVac innovative design makes it easier to change the oil in engines such as boats with inaccessible drain plugs. It works by creating negative pressure or vacuum power in the tank. Pumping the tank handle 40 strokes creates a powerful vacuum that it extracts the oil directly out through the dipstick tube. An average boat takes only 8-10 minutes to extract the motor oil, and without a mess. We all know how messy changing outboard motor oil and inboard motor oil is!
The Large Engine/Project Model comes with a special narrow suction hose to fit dipstick tubes to make your outboard oil change and inboard oil change easy. Plus, its tank has an 8 quart capacity allowing the user to make multiple oil changes of small engines too.
