Mercruiser 5.0 Oil change

So I went to change the oil on my 1998 Rinker Captiva 212 for the first time the other day.  Ran the engine for a few minutes to warm it up, fed the extractor tube on my hand pump down the dipstick tube and started pumping.  But the oil just sputters out at a very slow rate.  I must have pumped for at least 15 -20 minutes and only got about a quart of oil out.  Is there a trick to doing this?  Maybe my little hand pump just sucks so I'm thinking I will buy a 12v pump online.  Anyone had similar issues?  Also, how do I figure out what oil filter is correct?  I don't have the original manual but I tried looking up the part number on MercuryMarine.com on the partfinder but can't find it.  I purchased a 

Quicksilver 866340Q03 and it seems to indicate that it fits almost all Mercruiser engines but I want to be sure.

I’ve never had any luck with the hand pumps. I have this 12 volt pump, works pretty well. I drilled the middle of a washing machine hose so it will fit over the dipstick tube and screw on. I cut the other end to fit on the pump barb with a clamp.

My engine is a 1988 model 5.7 in a 93 rinker.  The wix oil filter number is 57009. 

The napa is 27099

The Quicksilver part number you have is correct.

Thank you for the advice.  I ended up getting a 12V pump and it worked much better than the hand pump.  Also, someone told me to go to Mercurymarine.com and email customer service my question about the filter.  To my surprise, they responded quickly and confirmed the filter I have is correct.  Plus they gave me a bunch of other recommendations on maintenance like correct oil, gear lube, etc.  Very helpful.
