I'm leaving my boat for the first time and want to shut off the sea cocks. The manual has  a diagram showing them all, all except the inbound cooling water for the engine. Anyone know where that sea cock is, please?

It's on the starboard side of the sail drive/gearbox. The cooling water for the engine comes in through the sail drive leg.

On my H400 2006 it's "somehow reachable" trough the hatch in the portside cabin.

Got it. Thanks so much, all. I did indeed find it through the hatch in the portside cabin.
