⚙️ Key Features

• Hydraulic trim raft and manifold assembly
• 7.594 kg
• Supersedes part number 21573365, which was catalogued earlier as a flap
• Provides the mounting and internal hydraulic connections for the trim cylinders, valves and hoses
• Position-specific, so identify it from the installation parts list for your engine

🔌 Function

Carries the trim cylinders and their hydraulic connections on one mounting and distributes oil between the valve block, hoses and cylinders.

⚠️ Common Signs of Failure

• Trim slow, uneven or drifting down when the boat is left
• Hydraulic oil weeping around the raft or its unions
• Oil level dropping with no obvious external leak
• Trim moving on one side only
• Corroded or eroded sealing faces and O-ring grooves found on strip-down

🛠️ Service Notes

• Renew the O-rings and seals at every union disturbed, and check the hoses for swelling or chafing while the raft is off
• Cycle the trim fully and recheck the oil level after fitting - air trapped in the raft shows up as slow or uneven trim
