Pinion Nut - Sierra Marine Engine Parts - 18-3719 (118-3719)


For 1968 and later Johnson/Evinrude 2-cyl, 40-55 Hp, and 3-cyl, 60-75 Hp outboard gearcases, the Pinion Nut - Sierra Marine Engine Parts - 18-3719 (118-3719) fits well. This pinion nut is well-constructed with premium, long-lasting, non-corrosive material that can resist the harsh sea climate. You can connect to the steering shaft using the Pinion Nut Engineered Marine Products - EMP Engineered Marine Products (10-08681) so that the gear will spin and move the rack when you turn the steering wheel. They join the steering shaft.This whirring sound indicates that the pinion nuts have failed when changing at different speeds while accelerating or decelerating. It does so because it rotates much more quickly than the vehicle's carrier component.

Key Features:

  • Made with high-quality materials for comfort and safety.
  • Consistent improvements in product efficiency, cleanliness, and environmental friendliness are well-made.
