Re: Stream or Spray?
OK I want to clear something up for myself... My motor is a '78 Chrysler 75hp. I've always thought that if the water pump is working correctly, water should flow/spray from the two exhaust/vent? holes on the back of the motor, just below the engine cover. I've always thought that these were the so-called "tell-tale" holes. However, I also have what I refer to as the "pee hole" just below the anti-ventilation plate, on the starboard side of the lower unit. I always thought that this lower hole was just to drain leftover water. I think I need to have this cleared up for me, because it seems that some posters on this board have used the two terms interchangeably...<br /><br />That being said, here's another issue. I've got my engine running on the muffs and it runs just fine. However after running it for about 30-45 seconds at a time I freaked out and shut it down because I could not see any water emitted from the upper holes. (After shutting it down, a few drops could be seen, but not at all what I would expect as a good amount of coolant.) At the same time, the lower hole had plenty of hot water running from it. I assume that my pump is working fine because of this, but it's still due for an impeller replacement so I'm doing that anyway. So, I guess what I'm looking for here is: what should I be looking for in the future to determine that the pump is working correctly? Thanks for the help, y'all.
