There should be a fairly steady spray. Most will go out under water with the exhaust. The water jacket on those outboards consists of a turn and a half of copper tubing placed around the grey iron sleave when it is put in the die casting machine. The copper is much more resistant the corrosion but harder to clean if it gets plugged up. It’s hard to find a reliable Roto-Rooter that small.
