48000-90J39 Suzuki/Johnson Trim Assemble Showa | Genuine Used Part

🔧 Product Description

Genuine Suzuki Showa Power Tilt and Trim Assembly - Part Number: 48000-90J39

A genuine Suzuki Showa hydraulic power tilt and trim assembly for selected DF100A, DF115A, DF115B, DF140A and DF140B four-stroke outboards. The unit combines the electric PTT motor, hydraulic pump, manifold, reservoir, centre tilt ram and twin running-trim rams. Earlier 90J35 and 90J37 assemblies use the same service family, but connectors, pump revisions and bracket geometry must be matched to the engine serial-numbered diagram.

🔌 Function

The electric motor drives the hydraulic pump to extend or retract the centre tilt ram and twin trim rams. The assembly raises the engine for trailering and shallow-water use, controls running trim under propeller thrust and hydraulically holds the selected position.

⚠️ Common Signs of Failure

• Engine will not raise or lower
• Trim motor runs but the hydraulic unit does not move
• Engine slowly settles after trimming
• Hydraulic fluid leaking from ram seals, manifold or reservoir
• Slow or uneven ram movement
• Trim works in only one direction
• Corroded motor wiring or pitted piston rods
