Need help changing water pump on Merc 150 EFI

[Loneshark]

I understand what you are saying now. I was trying to get a wrench in there to unscrew that particular fitting. In your earlier post I thought you were saying there was a quick disconnect up the hose. What I think confused me was the pics in the link you posted. Thanks everyone for all of your for the help especially Tete. I am going to give it a shot this evening. I will let you now the outcome.
