The simplest way to flush an engine is to turn off the thruhull, open the top of the raw water filter and just stick a garden hose in it. Turn the water on part way, it will fill the filter and overflow in the bilge. Start the engine at an idle, the overflow will stop and the engine will flush. Stop the engine after a few minutes, turn off the hose, remove it and replace the cap. No special caps or tee's needed and the system isn't pressurized which could pop a hose or pass water around the impeller back filling the exhaust.
