1972 50 hp Evinrude Question..Water output

Just bought a nicely restored classic boat..Powered by a nice two stroke 1972 50 hp evinrude with the Elec. Shift..

Have took it out a few times in the local river, my question is:

How much water should be coming out the two vertical "exhaust" slits?

At low speed its a pretty good dribble, out both slits.. I'm used to seeing a merc stream you know.. And at high speed, say 40.. its nadda , meaning no water coming out... Motor runs great besides that.. Just don't want to burn her up.. I know the impellar/pump system was replaced a few years back when the motor was rebuilt.. i want to know whats considered normal for this model.. Thanks in advance for any help..

at idle and low speed you get some water, at higher speeds most of it goes out the prop exhaust. you can put a tale tell hose on that motor. if iti has been a few years i would consider a new impeller, anyway. it is hydro-electric shift. http://forums.iboats.com/showthread.php?t=222677

I have exactly the same motor. Tassadaddy has helped me a lot with it on here. Mine dribbles at idle and low speed and then at higher speed more comes out.
Just a couple of things... Do you know about the electric shift seloniods in the lower unit. If one goes then the motor will go in forwards only. Its a fail safe so if theres a problem you can get back to the ramp. These seloniods are hard to get hold of ( not wishing to scare you ) and they can be expensive too.. If you get the chance to get a spares motor do so.... you will save a fortune. Other parts such as coils starters etc are easy to get hold of from the local johnson dealers.
If you are in florida a few have come up on ocala4sale in the past month or so. I know two are on at the moment.
