I think that motor was fresh-water cooled, meaning it has a heat exchanger on it and the water that is in contact with the engine parts is a closed circuit, with a wee pump.
Another wee pump supplies the external water (whatever the boat is floating in) to cool the heat exchanger.
I think the 2002 was an aluminium engine and so would not tolerate raw water cooling like my olde cast iron Volvo MD17C would do.
Make sure there is enough oil in that sump!!! and enough coolant in the primary cooling circuit!!!
Those aluminium motors do not tolerate being cooked like the old cast iron motors can tolerate (within reason).
