Hello.
I've got some problems with the cooling of my engine, and hopefully someone here is able to help me locate the issue.
From the top:
I was doing some service on my lower unit, changing the impeller and other parts, when I first noticed that the impeller was close to destroyed.
I ofcourse replaced the impeller, and I also had to remove some of the parts from the impeller as this was lying around in the lower unit (Looked like it had been running without water)
This did not actually help me anything
The problems escalated, and still I got no cooling in the engine.
The next ting I noticed was that there was some exhaust comming out of the water indication pipe going out of the engine, and realized that it must be a exhaust leakage into the water system.
So the next thing i had to do was remove the cylynder tops, replace the gaskets and also I had the cylynder tops to a mechanic, to check if they were flat, wich they were not.
I did this, and this did not either help.
The next thing i did was replacing all the parts to the impeller set, all the gaskets, and also the housing, and aswell the thermostats and blew compressed air and water with high pressure trough the water line, to be 100% sure that nothing was plugged up.
This picture will show you all i changed, from the parts #1 to #20.
This did not either help my problem, so the next thing I had to do.. Was to split the entire engine from the middle section of the engine, and checked for a exhaust leakage there.
The first thing I saw was not a pretty site, so i cleaned up, replaced all the gaskets and reinstalled everything.
This did not either help my problem.
Now I'm back controlling the Lower Unit.
I've tried to use a drill on the shaft in the lower unit, to see that the impeller blows water out, and it does.
I've tried to use a hose directly into the waterline from the middle section, up in the engine with the lower unit dismantled, and it works like a dream.
The only modification i got on the engine is a nosecone on the lower unit.
Can anyone help me to indentify the issue?
Thanks from Norway!
