How does that pan drain work exactly? Is it left on engine permenently or?
The pan drain plug is removed and the hose is connected permanently. Then you can put the other end of the hose anywhere you want. Mercruiser uses one that can be pulled out the bilge drain so you can gravity-drain your oil too. I don't really like that idea because it requires you to "crawl" under your engine and reach in there to stuff it through the bilge drain. It just lays in the bilge. That's a messy operation all by itself.
I used an ADEL clamp and clamped it directly to my port riser. When I want to change the oil I just connect the Moeller vacuum pump to the hose and pump it about 15 times. Hot or cold the oil is out in a couple of minutes.
It came with a couple of different plastic tubes that you would presumably stuff down the dipstick tube but that's a pretty messy operation too. You usually end up flinging oil around and you have this tube that you have clean off. The way I'm doing it there's no mess at all. The only source of a drip might be the hose you use from the pump to the tube when you disconnect it after you're done. If you let it sit a few min before you remove it most or all the residual oil drains out of the hose enough so that any drip is easily caught with a rag. I just use simple brass fittings to connect it together.
It works REALLY well and since you are connected to the pan drain you get it all out.
The hose comes with a cap that goes over the end but I don't worry about it leaking because the capped end is up so high.
