How to fresh water flush on Mercury 9.9
I did not see any obvious place for the water pickup.
Then I got the bright idea, I hope, that if I picked the engine up after running it and checked quickly I would see where the water ran out which might be the same place as the intake.
So I got to take a couple pictures, not the best standing on my head over the back of the boat.
The first one shows the stream coming from jut below the cavitation plate.
The second one is over exposed but shows the hole just above a bump.
How does one hook a hose up to such a difficult place. I don't see how standard muffs will work?
