Saltwater/brackish water

[nickmo]

My boat that has a 5.0 mercruiser alpha 1 gen 2 is docked on a creek that is brackish water. The boat is used there and mostly in full saltwater. Each time the boat returns to dock it runs through this brackish water.
Will this extend the life of manifolds and risers and the engine? It is raw water cooled.

Yes this will help to flush it out, the more time in the water the better. Should be using aluminum anodes
