I"ve dug around and found the possible problem ( stuck flush valve). My question is can I just cap the hose off and run her? Ran it the other day ( not capped ) with water ( hot ) coming out the tube. Temp stayed at 130 - port engine the same but no water coming from hose. Thought to replace valve, but would it be necessary? It works to flush, just backfeeds when underway.
Merc dealer is no help.

problem solved. The hose could be capped to stop the outflow of cooling water - but there is the slight chance that the motor would get an airlock from doing that. No idea what the consequences would be. So, ordered a new valve assembly which will solve the whole problem. Such a pain for what seemed to be a small issue. Anyhow - .
