2hp evinrude 1977 water pump issue

[dr1077]

Ok guys, where is the water from the waterpump supose to show on this 2 horsepower motor? And is there a way to put a waterflow indicator tube on this? and also if the water isnt pumping then that causes the engine to get hot fast which means the moter will die quicker right? I know a bit about small engines but outboards I am still learning,lol I finally got the engine to idle in slow but it dies like it gets hot, and I didnt see anything where the water was coming out from the lower unit, not even the exaust port, which I think that is where it is supose to show, I am not sure. so think I need to put a new impeller in the water pump.

I think the only indicator is the exhaust ports. If the cylinder head gets to hot to hold your hand on for more than 2 or 3 seconds, put a water pump in it.
