68 Evinrude 55 hp cooling system

[revkab]

I am just beginning to check out a 1968 55 hp Evinrude Triumph with hydro-electric shift outboard.

I put the muffs on it, and after a bit of guessing/poking/prodding, got the thing started and running. I noticed there was no water coming out of the two "water discharge and exhause relief" jut under the exhaust covers. Should there be? I shut the engine off pretty quick so I hope there was no damage.

The engine has to warm up enough to open the thermostat. That can sometimes take awhile running on a hose, it will also spit water out the exhaust hub of the prop. Hold your hand on the head as it's running to tell how warm it's getting.
