Product Description

679-45570-00-00 
Gear 2 (26T), Yamaha,
For Outboard: Yamaha 40

Features:

1. Precision Machined: The reverse gear is designed with precise engineering to ensure smooth meshing with other gears (like the pinion gear and clutch dog) for efficient power transmission.

2. Durable and Resilient: Made to handle the stress and torque associated with shifting into reverse and operating under load.

3. Corrosion-Resistant Coating: To withstand the harsh marine environment, the reverse gear is often coated or treated to prevent corrosion, particularly important for saltwater use.

Functions:

1. Power Reversal: The reverse gear enables the propeller to spin in the opposite direction, allowing the boat to move backward.

2. Engagement with Clutch Dog: Similar to the forward gear, it engages with the clutch dog to shift between forward, neutral, and reverse modes, controlled by the operator via the throttle/shift lever.

3. Torque and Power Management: It adjusts the torque delivered to the propeller when operating in reverse, ensuring controlled and smooth movement.

Maintenance Tips:

1. Regular Oil Changes: Ensure the lower unit's gear oil is replaced periodically. This keeps the reverse gear well-lubricated, preventing metal-on-metal wear and extending its lifespan.

2. Inspect for Wear: Regularly inspect the gear for signs of wear, such as chipped or damaged teeth. Early detection can prevent more serious gearbox problems.

3. Avoid Abrupt Shifting: Smooth, deliberate shifting between forward, neutral, and reverse helps protect the reverse gear and associated components. Abrupt shifting can cause unnecessary strain.

4. Check for Water Intrusion: Inspect the gear oil for water contamination (milky appearance). Water intrusion can cause corrosion and damage to the reverse gear and other lower unit components.

5. Flush After Saltwater Use: After operating in saltwater, flush the motor with freshwater to reduce salt buildup, which can lead to corrosion in the gear system.

Common Issues and Symptoms:

1. Grinding Noise in Reverse: Unusual noises when shifting into or operating in reverse may indicate that the reverse gear is worn or damaged.

2. Difficulty Shifting into Reverse: If it becomes difficult to shift into reverse, or if the motor slips out of reverse, it could be due to wear on the gear teeth or clutch dog.

3. Loss of Power in Reverse: A damaged reverse gear may not transmit power effectively, resulting in reduced or no propulsion when in reverse.
