My new 6.2L mercruiser engine has run a great season. I’ve logged 70 hours on it. About half of them have been In salt water. I’d like to install a freshwater cooling system on the boat so I can run in salt water worry free.
I’ve heard rumors though, that if I install a freshwater kit on a used engine which already has some corrosion in the water jackets, it’ll clog and ruin my cooling kit, and overheat the engine.
I just tore down a small block with 127 hours of salt use, and the water jackets are very rusty. About a quart of sand and rust dust poured out of the engine block onto the floor.
