The Yamaha 68V-45501-30-00 is a genuine Yamaha OEM drive shaft assembly used in select Yamaha F115 and LF115 outboard lower-unit assemblies. This vertical drive shaft transfers rotation from the engine crankshaft down through the midsection into the lower gearcase, where it drives the pinion gear and supports water pump operation.
The "-30-00" suffix is commonly associated with the extra-long 25-inch / X-shaft configuration. This part should be matched by exact model, shaft length, lower-unit diagram, and Yamaha serial/application lookup before ordering.
Key Features

Engine Compatibility
Common application context includes select Yamaha 115 HP four-stroke outboards by model, serial range, shaft length, and lower-casing diagram, including:
- Yamaha F115 inline-4 four-stroke models where specified
- Yamaha LF115 counter-rotation four-stroke models where specified
- Select F115TXR / F115XA / F115TLR and related 115 HP four-stroke model variants where the Yamaha parts diagram calls for 68V-45501-30-00

Use this drive shaft only where the Yamaha parts diagram specifically calls for 68V-45501-30-00.
Serial Number Fitment Notice
Confirm fitment by Yamaha model code, serial number, shaft length, rotation direction, lower-unit style, and exact lower-casing drive diagram before ordering. Yamaha 115 HP four-stroke models can use different drive shaft lengths, gearcase configurations, and lower-unit components depending on model year, transom height, rotation, and production range.
When This Part Needs Replacement
Replace the drive shaft if the original shaft is bent, twisted, heavily corroded, worn at the seal surface, damaged at the splines, pitted where seals ride, or has failed during lower-unit service. It should also be inspected during gearcase rebuilds, water pump service, impact repairs, and any lower-unit teardown where shaft condition affects sealing, alignment, or power transfer.
Installation Notes
Lubricate the upper driveshaft splines with the Yamaha-approved marine grease specified in the service manual before installation. Do not install the shaft dry. Inspect the crankshaft spline engagement, water pump base, impeller, driveshaft seals, pinion gear, bearings, shims, and related lower-unit hardware while the assembly is apart. Replace disturbed seals and gaskets as required by the Yamaha service procedure.
Verify shaft length before installation. If the outboard is a standard 20-inch long-shaft model, it may require a different drive shaft than the "-30-00" 25-inch extra-long version.

Parts Desk Insight
Drive shaft fitment depends heavily on shaft length and lower-unit configuration. A 25-inch shaft cannot be selected by horsepower alone, even within the Yamaha F115 family. Always confirm the model suffix, serial number, lower-unit diagram, and transom height before ordering so the shaft matches the gearcase, water pump stack, and crankshaft spline engagement.
