Mercury – Trim Limit Switch Kit | Controlled Tilt-Up Range | 899625K08

Overview

When an engine tilts too far, it can bump into brackets, rigging, or the transom—especially on smaller outboards. The Mercury 899625K08 Trim Limit Switch Kit keeps that from happening. It gives you a reliable upper stop so the engine lifts only as high as it should, protecting both the motor and anything nearby. Once installed, trimming and tilting feel more controlled and predictable, making day-to-day operation a lot smoother.

Key Features

• Tilt-Up Protection – Sets a controlled upper stop to prevent the engine from over-tilting into hardware or the transom.

• Factory Integration – Designed to tie directly into the power-trim circuit with a clean, OEM fit.
• Durable Marine Construction – Built to handle vibration, moisture, and regular trim-system use.

Performance & Practical Benefits

This switch adds an extra layer of protection to the tilt system, stopping the engine from climbing higher than it should. You’ll notice the benefit most when raising the motor at the dock, loading the boat, or trimming up in shallow areas. The stop feels clean and positive, keeping the engine from contacting rigging or climbing into a position that strains the bracket. Once set, it works quietly in the background and holds its adjustment season after season.

Why Buy OEM

Mercury’s trim limit components are matched to the motor’s wiring and travel range, which keeps the system consistent and reliable. Aftermarket versions often fail early or allow too much variation in the stop point. The OEM kit installs cleanly, communicates correctly with the trim circuit, and maintains a dependable limit without the need for constant readjustment.

FAQ

Q1: What signs indicate I need a trim limit switch?
If the engine tilts higher than normal or bumps into rigging or the transom, the limit function is missing or no longer working.

Q2: Does this change the engine’s normal trim range?
No. It only controls the final tilt-up height and does not affect on-plane trimming.

Q3: Is setup difficult after installation?
Most setups only require adjusting the stop point once to match your boat’s clearance.

Q4: Does this kit affect digital trim gauges?
No. It only limits tilt travel and does not interfere with trim-reading systems.

Q5: Can it handle continuous saltwater exposure?
Yes. The components are built for long-term marine use when installed and sealed properly.
