Atomic 4 cooling system flushing

Ray Hughes

Member I
The coolant discharge from my raw-water cooled A-4 varies from good flow to weak. Moyer Marine suggested flushing the system with a 50% water-diluted muratic acid solution. The local yard recommended "Salt-Away" as a better and safer flush. Any inputs? Thanks, Ray.

I have never heard of 'salt away', but did the acid flush as per Don Moyer, and it worked well. The acid could cause damage if left there too long (i.e. not flushed out thoroughly enough at completion), but he told me very few of his customers have problems after doing the job as he describes it.
