🔌 Function

Traps weed and debris in the raw water intake before it reaches the seawater pump and the heat exchanger behind it.

⚠️ Common Signs of Failure

• Overheating that eases after the filter basket is cleaned
• Weed, shell or plastic debris packed into the basket
• Air drawn in past a perished lid seal, so the pump loses suction
• Cracked bowl or lid, often after over-tightening
• Corrosion or scale inside the housing

🛠️ Service Notes

• Fit it in the suction line above the waterline, as the catalogue specifies, or it will not self-drain and will be awkward to open
• Five older references now consolidate into this one part, so an old parts list may point at a number that no longer stands alone
• Inspect the lid seal every time the basket is cleaned; a leaking lid loses pump suction without showing a water leak
• Install it in the cooling system's suction line above the water line
• Recommended rubber hose is 1140664, the 32 mm size
