Good To Know

Q: How do I confirm this PTO end fits my watercraft? A: Match the OEM number 420958123 and the model year 1999 GSX LTD 951 before ordering. Serial number ranges can vary, so check your hull's identification plate as well.

Q: Can I reuse the original hardware and driveshaft with this PTO end? A: In most cases the existing driveshaft and fasteners carry over when the splines are in good condition. Inspect the mating splines for wear before reassembly.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
