Ok, I pulled the foot on my 1959 Johnson 18 HP outboard, found the water pump and have a couple of questions. First off, the impeller has all the vanes and is very pliable. I will go ahead and replace it, but in the meantime.... <br />1) When I pulled the foot, there was no gasket where the foot joins the rest of the leg...is that right that there isn't a gasket there?<br />2) The output end of the pump is a copper tube (water tube I guess) that inserts into a rubber grommet up inside the leg. Would a pump rebuild kit include that grommet or whatever it's called?<br />3) The water inlet has me confused. On the back of the foot is a sorta rectangular shaped opening...in front of it is a screen. The screen part seems to go to a cast tube, but it seems to be a deadend, which makes no sense to have a screen if it goes nowhere...is there some type of internal tube that is cast into the housing?<br />4) If anyone can walk me thru the path of the cooling water, I'd appreciate it.<br />Rob
