oil change pumps

My Suzuki motor book talks about draining the oil by removing the plug and catching the used oil in a pan. Easy to do when the boat is on the trailer but it can be messy and not always convenient or possible when the boat is in the water and the hundred hours comes up. Shops seem to use a pump that goes in the dip stick hole. Do the pumps get it all, or is the little that remains not significant? Does it make a difference on motor brand? Some pumps have a rigid tube for insertion, and some a limp tube that had been coiled, so the tube was curled.

Any recommendations on pumps. Any thing else I should know before I go that route?

I use a pump to remove my oil, works great and gets all the oil as far as I can tell. I am not sure of the brand/model of mine but it has a 5 litre capacity and it is simple to use. Tug
 
I use a 12v pump to drain the oil from my generator as it is hard to get any type of pan under it for draining. Get a good quality one and like Brent said the oil must be hot(full operating temp.) If you begin pumping immediately after shutting off the hot engine and you change the oil and filter regularly there should be very little sediment at the bottom of the pan. I hold the tube outside the oil pan at approx. its lowest point and then hold my fingers at the top of the dipstick. Then when I insert it I know when the end of the tube should be at the bottom of the oil pan. Listen carefully and you can hear it hit the bottom. If you just push all the length of tubing into the dipstick hole it will hit the bottom and curl back up - perhaps above the oil level. Try to do this on the first shot because after the plastic tube is inside the hot engine for a couple of minutes it expands and can become tight in the dipstick tube. Also it helps to keep the pump as low as you can to keep the head or rise that the pump has to overcome to a minimum. Sometimes it helps to prime the pump with some clean oil first. Careful around the hot oil. I would also advise wearing latex gloves - any used fluid removed from an internal combustion engine is a known carcinogen.

Over the years I have used a number of different pumps to remove oil from engines. They are essential for inboard motors that have no drain plug, or one that is inaccessible. I started with a hand pump, moved on to a reservoir type with a manual vacuum pump, a cheap electric pump and have now moved on to a Jabsco 12 volt pump on a bucket. I'm in hog heaven now. The Jabsco is great. They all have a series of nesting tubing to get to the size appropriate for your dipstick hole. They all remove virtually all the oil and the mess is minimal. Manual pumping is tedious and gets old. Keep the tubing connections tight and you will have no mess. I use the pump on all the engines I maintain.

I have a Tempo oil extraction pump and love it. I use it for my cars, all of my boats and even my lawn tractor. It works well and removes all but the last drops of oil with NO mess. My boats are on boat lifts, so changing oil without having to put them on trailers is fantastic.
After looking up the oil extraction pump, I note that most sites show it no longer available, but West Marine shows almost the exact pump (Model # 11047123) currently available.
