Do outboard motors need to be flushed?
Regular flushing with freshwater is key to maintaining any outboard motor used in saltwater. Most outboard manufacturers recommend a freshwater flush after every use in saltwater to clear the cooling passages of salt residue and scale that can accumulate and impede the flow of vital cooling water through the engine.
How often should you flush an outboard engine?
A full flushing of the motors must be done after every use, and it’s recommended every six weeks if it’s been sitting in storage. It’s important to run the motors long enough for the thermostat to open, allowing the fresh water to flush the salt from the entire powerhead.

Would also remove the thermostat and zinc anode in behind thermostat.
Is it okay to start a boat motor out of water?
It is not recommended to start a boat without water. In most outboard and inboard engines, impellers (rubber pumps) are used to circulate water to the cooling system of the boat. If the impeller does not have water to cool off and lubricate, it will heat up very quickly and possibly damage itself.
