Removing oil overfill

[Bluey]

The old boatyard appears to have put too much oil in my 6LP. I've been warned that is Not A Good Thing, but that the excess can be pumped out through the dipstick hole. Anyone have a recommendation on an inexpensive pump for doing this sort of thing? I don't want an expensive pump at this point, and don't particularly want to take her back to the old boatyard.

I’ve had success with a $30 type oil dipstick removal dc pump from K-mart – they may have a boating section in your local store. Make sure that the oil in the engine is warm. Watch out for the recoil of the removal tube when removing it from the dipstick port. That tube was coiled up in the packaging and will try to resume its original shape. In doing so it can produce oil splatter all over the place… I also use the pump when I wish to take an oil sample.

Check that the end of the tube that goes into the dipstick port has a 45 degree end cut. Don’t draw from the bottom of the oil pan. Try to place the pump close to the dipstick port as much as possible in order to minimize head pressure…

Note – The $30 was a couple of years ago…

Good luck,

What Joe recommends would be a good choice. Even a hand pump would suffice. I would not worry too much about warming up the engine though. This time of year a multi viscosity oil flows easy enough as you are only looking to suck out some excess, not every last drop..

Disconnect the oil feed hose to the turbocharger. Turn the engine over but don't let it start. The oil will pump out thru the hose (into a container of your choice). You don't have to buy a new pump.
OR....use an outboard engine squeeze ball rig thru the dipstick. Cheap and easy. You can buy at Walmart.

Don't know what year your Yanmar 6LP is, but on many the end of the long oil dipstick is a male fitting that couples with a female fitting (which you can buy at a Home Depot or Hardware store) to attach to your pump. Saves having to put anything down the dipstick tube.
