Questions & Answers
Is this a genuine original part?
This is a premium quality aftermarket replacement part, manufactured to meet or exceed original equipment (OE) standards for fitment and performance on Tohatsu and Nissan engines.
How do I know if it is compatible?
We recommend checking the SKU/MPN and Cross Reference list provided above. This shaft is specifically for "Short Shaft" (15-inch transom) engines. If your engine is a "Long Shaft" (L), this part will be too short.
Does this include the lower drive shaft?
No, this listing is for the Upper Drive Shaft only. On the engine families listed in the Compatibility section, the drive shaft is typically a multi-piece assembly involving an upper and lower section.
