You will need to get an attachment for your hose to clamp over the water inlet slots in the lower unit. Any marine store should have them. It's very simple, just turn the water on so you have good flow to the engine and then start it and run for a little while. If you are in salt water I would recommend also buying a Salt Away kit so you can neutralise the salt in the engine as well at the same time. Also available at marine supply store.
