Boat Care Tips
One of the most important aspects of boat care is proper lubrication. With proper care and the right mix of products you can extend the life of your engine and prevent expensive repairs, and best of all, you can do most of this maintenance yourself. Now, before we give you some helpful hints, we want to dispose of some myths about oil and engine manufacturers.
First, you will not void your warranty by using oil other than the engine manufacturer brand. As a matter of fact, Sierra offers the most extensive warranty in the marine business. No engine manufacturer backs their oil and lubricants with a longer or more extensive warranty. If your engine is damaged because of the quality of a Sierra lubricant we will pay for parts and labor to repair, plus we pay for incidental expenses like haul-out and towing. Sierra offers the best warranty in the marine business, hands down!
Second, Sierra offers the widest variety of oils on the market to match your engine’s needs. 4-stroke, 2-stroke, gear lubes and engine greases. Sierra has the right lubricant for the job. Our oils are blended to the same high standards as the OEM oils and meet the same FC-W and TC-W3 certification standards. Sierra offers specific oils for your brand of engine, not a “one oil fits all” like some companies.

Fuel Line Assemblies & Primer Bulbs

Primer Bulbs & Fuel Line Assemblies
In 2011, the EPA required all primer bulbs and primer bulb assemblies to utilize low permeation components to reduce pollution causing hydrocarbon permeation through the hose and/or primer bulb by as much as 85%.
In response, Sierra introduced a new EPA approved primer bulb that exceeded the mandated permeation rate while maintaining Sierra’s traditional look, feel, and operational characteristics. Manufactured from a unique FKM material, Sierra’s primer bulb meets both EPA and CARB standards while providing outstanding warm/cold weather flexibility.
The Silverado 4000 is a rubber fuel line with fabric reinforcement that features a PVDF layer to prevent permeation. Designed to meet all EPA/CARB requirements and compatible with all blends of ethanol reformulated fuel, the Silverado 4000 is extremely flexible and kink resistant in all weather conditions.
