I used the Topside MVP vacuum canister made specifically for this type of thing. After warming the engine for a few minutes, you pump the air out of the canister and place a tube down the dipstick tube then suck out the oil.
It took a couple of cycles (pump/suck) but only took about 10 or 15 minutes.
The oil filter is mounted on top of the engine - black round cap on front of engine. The filter is a cartridge that mounts inside the engine. I used a filter "B" wrench to remove the filter. The filter kit includes the filter and several rubber gaskets.
I bought the Topsider at a boat supply store. Yes, I did use Mobil 1, 0-40 which I found at Autozone I believe.
I had given up on changing my own oil too but this is the easiest oil change I've ever done.
