A good way to remove calcium and build ups from outboard

This is a descaling set up. A bilge pump send descaler through leg cooling water intake to the power head, as if engine is running with impeller pumping. This is a save method to perform a descaling. After one hour, the liquid turns from pure green to darker brown, indicating dissolved solid off the inside of power head. Rinsing with fresh water when it is done. Sorry I put in 500 or so hours on my 9.9 kicker over years, not 500 hour per year
