📋 Kit Contents

• Sea water pump screws - Volvo Penta 22125080, quantity 4

🔌 Function

The screws clamp the pump cover or housing evenly so the impeller cavity and O-ring remain sealed under suction and discharge pressure.

⚠️ Common Signs of Failure

• Screw heads are rounded or corroded
• Threads are stretched or stripped
• Pump cover leaks after servicing
• Fasteners cannot be tightened evenly
• Incorrect screws contact internal pump components

🛠️ Service Notes

• Use the complete kit on the joint rather than mixing new fasteners with used ones — the screws are supplied together because the joint has to be clamped evenly
• Treat them as single-use items: many engine and drive screws are angle-tightened or stretch fasteners and will not give the same clamp load a second time
• Check that the threads and the faces the screws pull against are clean and undamaged, clear any old thread-locking compound out of female threads, and fit any washers supplied with the kit
• Tighten to the figures and in the sequence given in the workshop manual for your engine, including any angle-tightening stage, and only use a lubricant or locking compound where the manual calls for it
• Recheck for tightness after the first running period where the manual requires it, rather than assuming a new fastener will hold
