I have to strongly endorse this idea! I did a solvent flush on my outboard a few weeks ago. I ran the solvent through the outboard on a loop for a couple of hours and all kinds of nastiness came out.Not sure about the hard vs soft water or mineral content or ions........ but will say that HOT Fresh water is the best option for combating salt. Most folks have their water heaters already in their garage. It's really very little cost to install a H / C mix valve to your exterior hose bib and have that option available for rinsing dive gear, boats, trucks, dogs....etc! Just say'n!
Afterwards i flushed the motor with freshwater for about 30 mins. Then i took the boat out this week for a few hours. Suffice to say it had been thoroughly flushed after the solvent.
After this week's trip i decided to flush with hot water for a change. I used a tub to cycle the water through for about 20 mins. Afterwards i noticed there was more scale in the bottom of the tub that hadn't been removed previously, despite thorough flushing and running the motor.
I am a convert to hot water flushing!
