I'm new to the inboard powered boats. I always had outboards.
I have twin 6.2L Mercruiser Horizons with closed cooling, 2003, and 2006, salt water use. I realize there are flushing ports on the engines but they are not convenient to use. I would like to be able to easily flush the raw water side of the cooling system. to extend the life of the heat exchanger, manifolds and fuel cooling system.
I have read on another forum(diesel engines) that some people have installed a T between the strainer and and raw water pump and and ran a hose above deck with a shutoff or cap where it can be easily connected a hose. I think I would use both the shutoff valve and cap as a belt and suspenders approach, just in case the the shutoff valve was inadvertently opened when using the boat. The fresh water hose on the dock can supply more water than the raw water pump uses at idle so it would back flush the strainer and no salt water should be drawn in.
Any downsides to doing this?
