Specification of 679-45501-10-00 Drive Shaft Assy Long 679-45501-10 For Yamaha Mariner Outboard E C K T 40HP 2/4T

This Yamaha Mariner outboard drive shaft assembly is the long version. Part number 679-45501-10-00 fits specific 40 horsepower models. It works with Yamaha and Mariner E, C, K, T series engines. These engines are both 2-stroke and 4-stroke types.

This drive shaft is a vital part inside the lower unit. Its job is simple but critical. It carries engine power down to the propeller. It connects the engine’s crankshaft to the gears near the propeller. Without it, the boat doesn’t move.

The part is built strong. It uses high-quality steel. This steel handles the engine’s full torque. It endures constant rotation under heavy load. The shaft is precisely machined. This precision ensures smooth spinning. It minimizes vibration. It reduces wear on other parts.

The splines on each end are very important. The top splines lock into the engine crankshaft. The bottom splines engage the pinion gear. A perfect fit here is essential. It prevents slippage. It avoids damage. It ensures reliable power transfer.

This assembly replaces the original factory part. It matches the Yamaha specification exactly. Using the correct drive shaft matters. It keeps your outboard running right. It prevents breakdowns. It protects the lower unit gears. Always confirm this part fits your exact engine model and year before buying. Installing it requires proper mechanical skill.

Applications of 679-45501-10-00 Drive Shaft Assy Long 679-45501-10 For Yamaha Mariner Outboard E C K T 40HP 2/4T

This Yamaha Mariner drive shaft assembly (part number 679-45501-10-00) is a vital long shaft component. It fits specific Yamaha and Mariner outboard motors. These motors are the E, C, K, and T series models. They are all 40 horsepower engines. It works with both 2-stroke and 4-stroke versions of these 40HP motors.

The drive shaft’s main job is transferring power. It connects the engine’s powerhead up top to the gearcase down below. The powerhead is where the engine makes power. The gearcase holds the gears and propeller. Power flows from the crankshaft down through this drive shaft. Then it turns the gears in the gearcase. Finally, the gears spin the propeller, pushing the boat.

You need this specific long shaft assembly for motors needing the longer leg length. The long shaft is common for many boats. It positions the propeller correctly in the water. This ensures good performance and handling. Using the wrong shaft length causes problems. The propeller might not sit deep enough. Or it might sit too deep. Both situations hurt how the boat runs.

This part is critical for the motor to work. If the drive shaft breaks or bends, the engine loses power to the propeller. The boat stops moving. Replacing a worn or damaged 679-45501-10-00 assembly restores power transfer. It gets the boat running again. Regular inspection helps spot issues early. Look for wear, corrosion, or damage. Proper maintenance extends the life of the shaft and the whole lower unit. Always use the correct part number for your specific Yamaha or Mariner 40HP motor.

5 FAQs of 679-45501-10-00 Drive Shaft Assy Long 679-45501-10 For Yamaha Mariner Outboard E C K T 40HP 2/4T

This drive shaft assembly replaces the original part in your Yamaha or Mariner outboard. It fits 40 horsepower models. These include the two-stroke and four-stroke engines in the E, C, K, T series. Check your engine’s exact model number matches before buying.

You might need this part if your motor vibrates badly. Strange grinding noises from the lower unit are another clue. Difficulty shifting gears points to drive shaft trouble too. Damage from hitting rocks or debris often requires replacement. Ignoring these signs risks bigger engine damage.

Replacing it involves removing the lower unit. First, drain the gear oil. Disconnect the shift linkage. Unbolt the lower unit from the midsection. Carefully pull out the old drive shaft. Slide the new one in exactly the same way. Ensure the splines mesh perfectly with the engine crankshaft. Reassemble everything in reverse order. Use new seals and gaskets. Tighten all bolts to the specified torque.

This is an original Yamaha component. It carries the official part number 679-45501-10. It meets the factory’s exact specifications. You get identical materials and precision. It is not a cheaper aftermarket copy.

Yamaha manufactures this drive shaft in Japan. Their factories follow strict quality controls. This guarantees reliability and a perfect fit for your motor. Expect the same performance as the part originally installed.

Buy only from authorized dealers. Verify the part number on the packaging. Counterfeit parts look similar but fail quickly. Genuine Yamaha parts protect your investment.
