Engine is a 1979 Evinrude 9.9HP Model# 10924B.
I've noticed the relief ports in the midsection seem to be holding water. If I let the engine set vertical after running it seems to drain all the water out, but if I take the engine off the boat and set it on the ground with the prop and back of the engine facing down there will be a good bit of water drain out the exhaust relief ports.
The engine runs just fine and when the thermostat opens I get a mixture of exhaust and water coming out the relief ports. By all accounts everything seems to be working properly.
This engine should be completely self draining so I didn't think any water would be held in the mid section. My guess is there is some kind of blockage but I'm not sure where to look. I would appreciate any suggestions of where to look so I can get the engine completely draining of all water after use.
Thanks.
