Product Details

The Sierra 18-99528 Gearcase Gateway Valve is a critical protective component designed for outboard motor lower units. This valve helps prevent water intrusion into the gearcase by allowing water to drain out while preventing it from entering, protecting internal gears and bearings from damage.

Key Features:

  • Prevents water contamination of gearcase lubricant
  • Allows trapped water to drain while blocking incoming water
  • Direct replacement for worn or damaged gateway valves
  • Manufactured to OEM specifications for reliable performance
  • Corrosion-resistant construction for saltwater environments

Regular inspection and replacement of the gearcase gateway valve helps maintain proper lower unit protection and extends the service life of your outboard motor's drive components. This valve is an essential maintenance item for keeping water out of the gearcase oil system.

Easy to find the product and easy to order. Shipping took a little longer than anticipated but overall, it was a good experience

Box was in good shape product was undated. Finishing assembly tonight.

Enjoying the product but the dividers in the box were difficult to put in, and didn't fit well.

It’s the second time I ordered from here. The first time was a great experience. Prices were reasonable and shipping was quick.

Easy
