What Others Have Said, but to make your life....
easier, try to change the oil when it's warm. You could change the air filter, impeller, fuel filter, etc. first. Bleed any air then start the motor, run it for a few minutes until the engine gets warm, (make sure you have cooling water going to the engine). Running the motor for a few will warm the oil and lower it's viscosity allowing it to flow easier when you pump it out.
After you turn the motor off, wait a few minutes to allow the oil to drain back into the bottom of the engine and cool a little before you start to pump it out. The oil will pump out much easier now. Replace the oil filter and HAND tighten it. Tighting it with wrench will make your life a living hell when it's time to change it again. Don't forget to apply a thin coating of new oil to the oil filter gasket before you put it on.
However, you can pump the oil out without warming it up if you want or if it is not possible to start the motor. It will just take longer.
In the fall, when you put the boat away for the winter, change the oil then.. One less then to do in the spring.
