How it Works

PRE-FLUSH

  1. BORESCOPE: Heat Exchanger, Cooler (Trans), and other systems where Zinc and or visual openings are accessible.
  2. RAW WATER PUMP: Visually check mounting, possible leaks, and any other issues.
  3. SEA COCK: Check valve for operational functionality.
    Note, Sea Cock Valve, even in a closed position can allow for seepage if compromised.
  4. Sea Strainer: Visually check Sea Strainer for grass build-up and cylinder clarity.
  5. Zincs: Check for wear and leaks and replace as necessary.
  6. Hoses / Hose Clamps: Inspect for clamp replacements or double clamp as necessary.
  7. Run Engines: Check for issues that could prevent flush, hull outflow exhaust/water stream, and color of smoke if any.

BARNACLE FLUSH

  1. Set up: Prep equipment and boat prior to flush.
  2. Boat protection: All surfaces are protected with Blue Diamond and waterproof tarps. Note, engines are NOT running during flush procedures. 
  3. Plumbing: Properly connect lines to achieve full circulation and run fresh water through system to check for leaks prior to adding the Barnacle Buster descaler.
  4. Flushing: Flushing rate is over 1,200 gallons per hour for a minimum of 1-2 hours per engine. Forward and reverse flush ensures capture of one-way particles. Check for change in color and odor signifying breakdown of calcium deposits. A filter bag captures particles such as broken impellers, zincs, and other foreign matter that should not be in the system. All systems are flushed with fresh water.

POST FLUSH

  1. BORESCOPE: Heat Exchanger, After Cooler, and other systems where Zinc and/or Hose openings are accessible to confirm results post flush.
  2. Zincs: Replace as necessary.
  3. Systems: Connect all Hoses, exhaust riser lines, prop shaft, and seal lines per checklist.
  4. Sea Cock: Ensure valves are open prior to starting engines.
  5. Run Engines: Check for leaks and exhaust flow from hull.
  6. Coolant: Test coolant properties and overflow level.
  7. Hoses / Hose Clamps: Check all Hoses, Exhaust Riser Lines, Prop Shaft Lines, Sea Cock Lines ensuring proper seal.
  8. Report: Full service report with photos emailed to you confirming flush results.
