Why It Matters
San Diego harbor water has moderate mineral content. Scale accumulates in heat exchangers and restricts cooling. Left unchecked, you\'re looking at overheating, cracked heat exchanger ($800–2000 to replace), and potential engine damage. Annual descaling costs $150–200. One emergency repair costs 5–10 years of preventive maintenance.
How Mark Does It
- 1.Close raw water seacock
- 2.Remove raw water strainer and inspect basket for debris or scale
- 3.Introduce descaling solution (citric acid or commercial marine descaler) into system
- 4.Run engine at low RPM to circulate solution through heat exchanger
- 5.Flush system with fresh water until discharge is clear
- 6.Inspect all hoses for soft spots or bulging; replace as needed
- 7.Reopen seacock, run test cycle, confirm steady cooling
