I have had the local boatyard do my oil changes on my ob but will probably do it myself now. Is there a drain or do you have to pump it out thru the dipstick with an oil pump?

How messey is changing the filter? It looks like as soon as you crack the seal you will have some spilage.

Not sure what motor you have, but for 150, Yamaha says this:
Realizing the need to build cleaner-running outboards, Yamaha built the F150 to meet and exceed the 2006 Federal EPA emission standards and the 2008 California Air Resources Board (CARB) emission standards years ahead of time. In fact, the F150 attains a 3-Star Ultra Low Emissions rating from CARB, the highest rating CARB bestows on outboards.
An automatic oil-draining device drains the remaining oil from the oil filter to prevent oil spillage during oil filter changes. The oil stick tube extends down to the bottom of the oil pan allowing for better precision when checking oil levels and allowing the use of a suction tool for quick and easy oil changes.

wish all marine engine manufacturers would make changing oil filters as easy as your BMW. I did have good luck yesterday changing a Yamaha F225 oil filter. Take the filter cover off, loosen the filter up a bit, put a small zip lock bag over it, tilt the engine all the way up and then spin off the filter. All of the residual oil and filter go into the zip lock. Not one drop in the belly pan

Yeah, that is what I thought...thanks. I will give it a go tomorrow. (225hp)
The bag thing is interesting. The way the filter is stitting, it does look like it drains. Won't know until I try it.

I was the one who 1st posted that idea for thew zip loc bag on the hull truth!
On the 200 & 225, remove the engine fuel filter to gain more room and also, use a small spring clamp to hold the zip loc bag on tight to help prevent spilling when tilting engine up & down..
Tilt the engine up and down a few times and you will get out more oil.
