1963 3hp evinrude: think I've got cooling problems

[207Rebel]

Anyone know if I should be having a solid stream of water out of this old motor while it's running or if it's supposed to only spray water? It sprays constantly so its definitely getting water, I blew through the holes with an air hose and air flows well, but it only sprays water. I have very limited knowledge with outboards and am curious if I'm chasing an imaginary problem. Thanks for the help.

It just mists out of those holes.-----But think here.--------The motor does NOT have a warning system.----The motor does NOT have an overheat shutdown feature either.----So if you do not know the age / condition of the impeller you should install a new one now----You need to fill the test tub to the top as well.-----There is not enuff water above the pump !.

So it is supposed to be more of a spray then a stream? Perfect, I was considering changing that impeller because I know they go bad with age, How would I go about pulling this apart to get at the impeller? Not certain how that's done. Also the test tub was full but I had just finished running it with a little load under her to see if it was running right. (I try to keep it as full as possible)

4 screws and the lower unit is off.----Then the pump is right there on top of the lower unit.
