All-in-one, built-for-ease installation

The unit combines the hydraulic pump, motor, and built-in reservoir in a compact package. This integrated design reduces leak points and external components, delivering a cleaner, more robust installation that’s easier to service in the field.

Simple, three-wire wiring for quick setup

Engineered for straightforward 12V DC operation, the harness uses clearly labeled connections: Blue for Up, Black for Ground, and Green for Down. This color-coding makes diagnostics faster and installation safer, even in cramped engine rooms.

Robust compatibility and precise fit

Designed as a reliable aftermarket replacement for Mercruiser Alpha/Bravo and Volvo sterndrives, this unit fits the common installation space with a footprint of 172.8 mm (L) × 150.8 mm (W) × 274.1 mm (H). While some Volvo connections may require minor adaptation, most installations align with factory expectations.

Performance specs you can trust

• Up pressure: 105–130 Kgf/cm2
• Down pressure: 50–60 Kgf/cm2
• Maximum pressure: 170–210 Kgf/cm2
• Steady hydraulic flow: 3.5 LPM

These specs translate to controlled, responsive trim and tilt under varying load conditions, helping maintain optimal hull attitude and spray pattern for safer, more efficient operation.

Direct OEM replacement cues

This unit replaces original components such as Mercury/Mercury Marine 14336A20, 14336A8, and 88183A12. Some installations may require minor connection adjustments, but the overall replacement path is straightforward, minimizing downtime and sourcing effort.

Ready-to-install from a trusted source

Ships as a complete, ready-to-install module from a local supplier. The integrated reservoir reduces the number of external parts you need to source, enabling a cleaner installation and fewer potential leak points. With clear wiring and a proven, compact design, you’ll experience faster diagnostics and dependable trim/tilt action from launch to landing.

Who benefits most

Ideal for boat owners looking to restore factory-like trim/tilt performance on Mercruiser Alpha/Bravo or Volvo sterndrives, marine technicians performing service or repairs, and DIY installers seeking a dependable, all-in-one solution that saves time and reduces downtime on the water.

Practical tips for best results

• Verify mounting space before installation to ensure the unit’s dimensions fit your stern drive compartment.
• Follow the 3-wire color scheme during wiring for safe, reliable operation.
• Check hose routing for kinks or sharp bends to preserve smooth flow and responsiveness.
• If your Volvo setup requires adaptation, plan for a minimal, straightforward connection adjustment rather than a full rewire.
