[C320-list] Running engine with seacock off?

[Graeme Clark]

Oops
Finally did it
Started the engine and let it idle for a few minutes then slipped my lines and gently motored off
Suddenly realised I hadn’t turned on the seawater cooling seacock
Turned it on. Water coming out of exhaust. No external signs of damage to exhaust hose or water muffler
But will there be internal damage?
Am I risking sudden hose rupture for example?
As I recall it’s nigh on impossible to remove hoses without damaging them
Ideas?
