Upgrade your outboard's performance with the Sierra 18-6817 Tilt & Trim Motors, engineered for reliability and durability in demanding marine environments. These all-new motors go beyond basic replacements, incorporating smart design enhancements that tackle common failure points like wear from saltwater exposure and heavy use. Boaters trust Sierra for parts that deliver smooth, effortless motor adjustments, whether you're trimming for optimal planing or tilting for trailering and beaching.
Built from the ground up with marine-grade components, these motors prioritize longevity and seamless integration:
Unlike remanufactured options that recycle old weaknesses, every Sierra 18-6817 is brand new, ensuring consistent power and quiet operation from day one.
Imagine effortlessly raising your outboard over shallow sandbars or fine-tuning your propeller angle for peak speed without straining a hydraulic ram. The Sierra 18-6817 delivers that precision every time, reducing downtime and boosting your on-water confidence.
Boat owners report smoother operation and noticeably less noise, turning a routine maintenance chore into a quick confidence booster.
Swapping in a Sierra 18-6817 typically takes under an hour for DIY-savvy boaters. Start by safely supporting the outboard, disconnecting power, and removing the old unit. Match the included harness directly, test relays before full reassembly, and cycle the system on the water to confirm smooth action. Always rinse with freshwater post-install to protect those copper bushings from the start.
Pro tip: Inspect hydraulic lines for leaks during the process—pairing a new motor with fresh fluid maximizes lifespan.
