These are probably stupid questions but: what am I looking for to make sure my water pump is pumping? Some mentioned "look for that telltale spray" but since this is my first boat I'm not sure what I'm looking for. Also, am I looking for water coming out of that tube that sticks out of my lower unit (is this the peehole?). My motor is a Merc 115 inline 6, 78 if that makes any difference.<br />Thanks, you all have been very helpful and I am now obesessed with this website...
