🔧 Product Description

Genuine Suzuki / Johnson Showa Trim Manifold and Cylinder Subassembly - Part Number: 48503-92J04

A genuine Suzuki Showa hydraulic manifold and trim-cylinder subassembly used within the DF140 and Suzuki-built Johnson 140HP power trim and tilt unit.

🔌 Function

The manifold routes pressurised hydraulic fluid between the electric pump, tilt piston, trim pistons, check valves and manual-release circuit. It allows the engine to raise, lower and remain locked at the selected angle.

⚠️ Common Signs of Failure

• Engine will not hold trim
• Hydraulic fluid leaking from the manifold or piston seals
• Slow or jerky movement
• Trim works in only one direction
• Internal bypass causing the engine to settle
• Corroded cylinder rods
• Manual-release valve leakage
