WSM Jet Pump Vein Stator for Yamaha Waverunner & Sport Boats 800-1300cc 1999-2018 – Replaces OEM 66V-51315-00-94, 6B6-51315-00-94 – Part # 003-730

Restore smooth jet pump performance and improve handling with this premium WSM Jet Pump Vein Stator. Also known as the impeller duct or vane guide, this critical component sits directly behind the impeller and straightens water flow for better thrust, acceleration, and top speed.

Over time, the original vein stator can wear, crack, or suffer damage from debris, leading to vibration, reduced pump efficiency, loss of speed, and poor handling. The WSM 003-730 is a high-quality direct replacement that matches OEM specifications for a perfect fit and reliable performance.

This stator is designed for the popular 155mm / 75mm bearing carrier jet pumps found on many Yamaha models.
