🔌 Function

The kit prevents seawater entry and lubricant or hydraulic leakage around the trim-sender housing and adjoining drive joints.

⚠️ Common Signs of Failure

• Water has entered the sender housing
• Trim sender is being replaced
• Seals are flattened, cut or hardened
• Corrosion is visible around the housing
• Later kit 23587207 is specified for the drive serial

🛠️ Service Notes

• Fit every item in the kit at the same time; the kit is made up for one job and reusing an old seal alongside new ones is where leaks come back from
• Clean and dry the sealing faces and grooves completely, taking off old gasket and sealant without scoring the metal
• Inspect the shaft or bore each seal has to run on — a scored or corroded running surface will cut a new seal straight away
• Lightly lubricate O-rings and lip seals with clean fluid of the type the system carries, and fit lip seals square with the lip facing the same way as the original
• Assemble and tighten in the order and to the figures in the workshop manual for your engine, then pressure-test or run up and check for weeps
