🔌 Function

Carries raw sea water from the intake to the pump, flexing with the engine's movement without splitting.

⚠️ Common Signs of Failure

• Sea water dripping or spraying from the hose or its clips
• Hose gone soft, spongy or ballooned near the ends
• Cracking or perishing visible when the hose is flexed
• Hose collapsing under suction so the pump loses prime
• Salt crust building up around the clip bands

🛠️ Service Notes

• The superseded numbers 3582721 and 3582722 also appear against hose 861739 and repair kit 861671, so identify this one by the intake-to-pump run rather than by an old number
• Renew the hose clips with the hose, and check the pump and intake spigots for corrosion while the hose is off
