Rookie Question on cooling..200 M2 DFI

[Heatsink56]

Merc 200 M2 DFI utopia 2003... what pushes the water through the block to cool it off.. aka water pump? i've tried searching impeller but all i'm getting is the actual prop impeller that pushes the boat. I know i'm a rookie and all but this seems like it should be a common part to look up. ????
what am i missing, Thanks in advance

There is only one impeller in the system. If your boat will move, the cooling water is flowing. No rubber to wear out.

HOWEVER- this does not mean your cooling system is perfect. You may have blockages somewhere. Most common place is hose from cyl. head to pee hole. Bugs love to build in that hose. If hot water can't get out, cool water can't get in.
