Since my boat is on a lift, I run the engine out of the water every single time it returns to the lift. While still in the water but held in place by the lift with the engine running, I connect a freshwater hose to a tee in the raw water cooling line between the sea strainer and the raw water pump, turn on the water, and lift the boat out of the water, without shutting the seacock. There is enough freshwater flow to supply the engine for the few minutes it takes to rinse the system while letting excess flow out the open seacock via the strainer, rinsing them as well. I shut the water off just before shutting the engine down.
