Additional Information

Sierra has a 56-year history as a top global producer of marine industry aftermarket engine and drive parts. In 2022, we broadened the SIERRA brand's appeal to encompass a variety of items for the aftermarket boating industry in addition to items for use on land.

In addition to the extensive maritime brands formerly known as Shields and Moeller, the SIERRA brand includes the whole SIERRA Marine product ranges. The Prime Line brand for ATV/UTV and outdoor power equipment markets, as well as additional aftermarket parts and accessories for land-based applications, will also fall under the new SIERRA Brand umbrella.

The SIERRA name is synonymous with high-quality, time-tested aftermarket goods that are backed by the best customer service and support in the market throughout all land and maritime markets. To anticipate and address client needs, we are always developing new products and technology.

Being in charge of your ship means having all the information at your fingertips. We have what you need to stay in control, whether you're determining wind direction, speed, or water depth.

Without a well working engine, there is no adventure on the water. Stock up on all the parts you'll need to keep yours running smoothly and conserving fuel so you can relax and enjoy the water.

We take giving the appropriate gear for the job seriously since we know how serious you are about maintaining your vessel to keep it in top condition. Browse our selection of products to easily complete any repairs or assembly.

Sierra  marine products that are engineered to surpass today’s high horsepower engine demands and stand up to the harsh marine environment. All marine products both meet or exceed the original equipment part it replaces.
