Sierra 18-2353

Keep your outboard motor shifting smoothly with the Sierra 18-2353 Shift Bushing Assembly, a reliable replacement for the original Mercury component. Designed for precision fit and long-lasting performance, this bushing assembly restores crisp gear engagement, preventing sloppy shifts that can lead to hesitation or missed gears during critical moments on the water.

Precision Engineering for Reliable Shifting

Crafted from high-quality, durable materials, the Sierra 18-2353 handles the rigors of saltwater exposure and constant mechanical stress. Unlike worn bushings that cause vague linkage or grinding noises, this assembly ensures tight tolerances for responsive throttle control. Boat owners rave about how it revives older engines, making them feel factory-fresh without the premium price tag.

Essential Features That Stand Out

• Direct replacement for OEM shift mechanisms, eliminating guesswork during repairs.
• Corrosion-resistant construction to combat marine environments.
• Easy integration with existing shift linkages for minimal downtime.
• Backed by Sierra's reputation for marine-grade reliability.

Perfect Fit for Popular Mercury Outboards

This shift bushing assembly fits a wide range of Mercury and Mariner engines, commonly found in 40-125 HP models from the 1980s through early 2000s. It's a go-to part for technicians servicing inline and V6 powerheads where shift cable play becomes an issue. Always cross-reference your engine serial number to confirm compatibility, ensuring seamless upgrades for your specific setup.

Spotting Wear Before It Strands You

Listen for clues like unusual clunks when engaging forward or reverse, or feel for excessive play in the shifter handle. A failing bushing can mimic cable stretch, but replacing it often solves multiple symptoms at once. Proactive swaps during routine lower unit service extend gearcase life and keep your adventures uninterrupted.

Pro Tips for a Flawless Swap

Start by securing your boat on a stable trailer or hoist. Disconnect the shift rod, remove the old bushing with a gentle tap from a soft-face hammer, and lubricate the new Sierra 18-2353 with marine grease before installation. Test shifts in neutral water before full throttle—smooth operation confirms success. Pair it with fresh shift cable adjustments for optimal feel.

Why Sierra 18-2353 Beats the Rest

Sierra parts like the 18-2353 prioritize affordability without skimping on quality, using materials tested against OEM specs. Independent mechanics trust them for their consistent performance in harsh conditions, from freshwater lakes to coastal bays. Invest in this bushing to avoid costly downtime and enjoy confident control every outing.
