Oil evacuation Yanmar 315

[FIVEPLAY]

One of my diesel mecahnic's first comments when he looked over my Yanmar 315 was that he was surprised that there was no port to easily drain the oil. He recommended, rather matter of factly, that he add one in the spring. Looking over this site it seems as if others have actually had this done. I am curious if anyone knows how this would effect the warranty on the Yanmar?

I use an electric pump out that goes down the dipstick tube. Next time I'm having work done I plan on adding a new oil plug with a drain feature. You still need a way to get the oil out though. There's not much room for a pan under the engine.

Here's what we installed in my 6LP. This was purchased through a Yanmar dealer. I would contact Mack Boring to discuss the effect on warranty but do not see that it would be an issue but only MB could confirm that.

RobS,
Do you just plug the other end or did you install a valve? I'm assuming you installed an electric pump. (I can't remember the brand name of mine)
The problem with mine is that the previous owner installed a valve under the pan. I have to crawl under, connect the hose, open the valve, connect the other end of the hose to the pump.
Last time I just let a mechanic do it. Too much crawling under for these old, I mean mature, bones.

John, I have a portable pump & bucket setup so I will continue to utilize that via this setup rather than removal through the dipstick tube. The end of the house has a fitting in it to cap it off. I don't see the need to install a pump in the boat for the few times a season the oil is changed.

Gee, that sounds like way too much work. The Yanmar 6LP has a tube that runs from the bottom of the dipstick tube down into the oil pan. I use a "Big Boy" oil vacuum pump. The larger hose supplied with it simply fits over the end of the dipstick tube and sucks that old oil right out. The drawback is that the can supplied doesn't hold all of the oil that the Yanmar requires so I carry a 5 gallon bucket to pour my drain oil into. Two cycles with the Big Boy will empty the pan. It is clean, neat and fairly fast.
