Installation Guide
- Ensure the outboard engine is securely supported and in the fully tilted-down position. Disconnect the battery for safety.
- Locate the existing tilt thrust rod on the clamp bracket assembly. Inspect for corrosion or damage.
- Remove the spring from the old tilt rod by carefully compressing or unhooking it from its mounting points.
- Unscrew or detach the old tilt thrust rod from the bracket. Note the orientation and any washers or spacers.
- Clean the mounting surfaces and inspect the bracket for wear or cracks.
- Position the new stainless steel tilt rod into the bracket, aligning it with the original mounting holes.
- Secure the rod with the original fasteners (or new hardware if provided), tightening to manufacturer torque specifications.
- Install the new spring onto the tilt rod, ensuring it seats properly in the designated grooves or hooks.
- Verify that the spring tension allows smooth tilt operation without binding.
- Reconnect the battery and test the tilt mechanism through its full range of motion.
- Check for proper alignment and ensure no unusual noise or resistance during operation.
- Perform a final visual inspection and secure all fasteners before returning the engine to service.
