Sierra 18-6793 Tilt-Trim Motor-Honda & Suzuki Product Description
Upgrade Your Outboard with Reliable Tilt-Trim Performance
Restoring smooth operation to your Honda or Suzuki outboard starts with a dependable tilt-trim motor. This component handles the essential up-and-down movement of your engine, making trailering, launching, and beaching effortless. When the original wears out from saltwater exposure or heavy use, replacing it promptly prevents strained hydraulics and potential safety issues on the water.
Engineered for precision, this motor delivers consistent power without the hesitation common in failing units. Boaters report quicker response times and quieter operation, extending the life of connected trim rams and seals. It's a straightforward swap that gets you back to reliable adventures.
Perfect Fit for Popular Honda and Suzuki Models
Designed as a direct replacement, it matches the specs of many mid-range outboards. Common applications include Honda models from BF40 through BF150 series, and Suzuki DF40 to DF140, covering both tiller and remote steer setups. Always cross-check your engine's serial number for exact fitment, as variations exist across years.
- Honda BF series: 40-150 HP
- Suzuki DF series: 40-140 HP
- Power trim and tilt systems
Its OEM-equivalent gearing and shaft length ensure no modifications needed, saving time during install.
Key Features for Long-Lasting Durability
Built tough for marine environments, this motor resists corrosion with sealed bearings and high-grade brushes. The robust housing withstands vibration, while efficient windings reduce heat buildup during extended use.

Users in salty conditions praise its longevity, often outlasting stock motors by handling electrolysis better through superior materials.
Step-by-Step Installation Guide
Swapping out a tilt-trim motor is a weekend warrior project with basic tools. Disconnect the battery first for safety.
- Remove the cowling and access the trim assembly.
- Unplug wiring harness and detach hydraulic lines if needed.
- Unbolt the motor from the pump bracket (typically 2-3 bolts).
- Align new motor, secure bolts to spec torque (around 10-15 ft-lbs).
- Reconnect wires—note color codes for up/down.
- Refill hydraulic fluid, bleed air, and test operation.
Pro tip: Grease pivot points during reassembly to minimize future binding. Full function in under two hours for most.
Spotting and Troubleshooting Trim Motor Issues
Early detection saves bigger repairs. Listen for grinding noises or sluggish movement—these signal worn gears. If the motor hums but doesn't move, check relays or fluid levels first.
| Symptom | Possible Cause | Quick Fix |
|---|---|---|
| No response | Blown fuse or bad switch | Test voltage at motor |
| Only tilts one way | Reversed wires | Swap leads |
| Slow or jerky | Low fluid or air | Bleed system |
A fresh motor often resolves hydraulic woes by providing steady pressure.
Maintenance Tips to Maximize Lifespan
Keep it running strong with simple habits: Rinse with freshwater after every saltwater trip, inspect wiring for chafe, and cycle the trim weekly to distribute fluid. Avoid max tilt positions for storage to ease gear stress.
Pair with quality trim fluid for optimal performance—synthetic blends fight foaming better in hot climates.
Why Boaters Trust This Replacement
Backed by rigorous testing, it mirrors factory performance at a fraction of dealer costs. Independent reviews highlight its value, with many noting seamless integration and zero warranty hassles. For weekend warriors to charter captains, it's the go-to for restoring tilt-trim confidence.
