for decades we brought our boat to the local marina for general maintenance, oil-changes and fixes. It was just the cost of having a boat. Oil-changes were part of the overall bill and never cheap. After some youtube browsing I came across a guy in Florida showing how oil changes are done on Volvo Penta engines. I could not believe how easy, clean and fast it was. Long story short, I bought the recommended Jabso vacuum extractor pump, the respecitive oil filter from NAPA and oil from Canadian Tire when their Penzoil sale was on. (<30 bucks per 5l, full synthetic premium). Did the oil-change after a few a boat ride, (after another 15+ minutes of cool down time). The pump sucked it out via the dipstick pipe effortless. Be a little careful, the oil is still warm to hot and the pump has a metal housing => pump gets hot as well. after roughly 3 minutes pumping, the oil was out, not a single drop spilled in the boat. Filter change was slightly harder due to the location of the oilfilter on our 4.3GL Volvo. with the right filter crown socket that wasn't too hard either. Pro Tip: Put a ziplock bag over the filter when removing the old one, this catches some oil that is dripping out of the filter when removing. All in all, can highly recommend that pump. Cost is around $80 CAD in most cases.
My previous Jabsco oil change pump was purchased in 1997 ($49), was used every year, and finally in 2021 the rubber ends cracked and broke off.
Hopefully this new one will provide just as good a service life. The rubber ends appear to actually be vinyl (a little stiffer) so we'll see if it can handle the abuse. The output hose is also vinyl - and very stiff. I prefer my vintage one, and will swap it out.
You can never get these pumps completely oil free when you store them, so I keep it in an aluminum tray, with an oil pickup rag.
Simple & reliable. If I had to change the oil on 10 engines a day, this would not be the pump to use - but for weekend warrior it is perfect.
Just did an oil change on a Merc 3.0. What a handy tool that says. If you buy one you will find it hard to get the discharge hose on I heated mine up a little bit over a stove and also did that to straighten the holes a little bit but then it slid on very nicely. Make sure you warm up your motor and the oil first, it will make it a lot easier to get the oil out. I hope this lasts for a while, a few seasons at least, But for now I am very happy with this came quickly and as advertised
You have to make sure the oil is up to operating temperature, if you have 2 engines you will have to run the 2nd engine again prior to using the pump as the oil must be worm/hot for it to flow... this pump require you to continuously pump, only took 15 -20 minutes per engine (Mercury 496 MAG DTS). Works great only engines with threaded dip stick.
Do yourself a favor and get regular clear tubing instead of the hard black plastic tubing that comes with the pump, much easier to work with and you can cut it to the length that works for you. Drained my 7.5 liter boat engine in about 5 minutes with no real effort or any mess. Just make sure to heat the oil up prior to pumping.
