It will take longer than that......might be closer to a minute or so. What method are you using to supply the engine with water? If you are using the bucket method, you can see the water level in the bucket change as the water is being sucked up by the raw water pump.

If you have a drain hose run it down thru the plug in front of the engine, warm up the engine then drain oil out of the hose, replace bolt on drain hose and add your favorite oil and filter

My water pump is always has a new fresh impeller every spring first thing. Screens are clean and water has been back flushed. Everytime I start my boat I usually raise the cowling after blower has cleared the bilge. Then I start the engine. I get to hear it, see it, and I reach over to the intake raw water hose and feel for coolness. Coolness means that raw water is going towards the thermostat neck.

Nice purchase. I don't think your boat is new enough to have an oil drain hose attached to the oil pan. There are a few options, most of which require a suction pump of some sort to draw the oil out through the dipstick tube. The cheapest method is a hand pump. There are pumps that attach to a drill (don't care for these too much. SKIDIM as well as a million other places sell extractor pumps http://www.skidim.com/products.asp?dept=1054
