I gave the A4 an acid flush as prescribed by Don, my blend might have been a little higher percentage (40% muratic acid to 60% water) for 15 minutes.
I then ran the engine with fresh water for 10 minutes to flush the acid out.
I had to leave the boat for an hour to get antifreeze.
Once back the engine would not start, I checked the dipstick and found water in the oil.
What are the chances water that was in the bucket siphoned back into the engine vs acid burning a hole through the water passage vs the water pump leaking?
