Gaskets Kit, Oil Seals and O-rings

Seal kits, including oil seals and O-rings, are essential components for the preventative maintenance of Evinrude, Johnson, and OMC marine engines. A worn oil seal or damaged O-ring can seriously compromise engine performance, leading to oil leaks, water intrusion, and, in the worst-case scenario, irreparable damage.

Why choose genuine BRP parts from Nautica Basile?

Nautica Basile exclusively selects genuine BRP parts, designed and manufactured to the highest standards for Evinrude, Johnson, and OMC engines. These parts guarantee perfect compatibility, optimal sealing, and superior durability compared to aftermarket alternatives. Choosing genuine parts means protecting your investment and ensuring the longevity of your marine engine.

When should you replace your gaskets, oil seals, and O-rings?

Replacing gaskets, oil seals, and O-rings is recommended during routine engine maintenance, typically every 100-200 hours of operation, or whenever you notice oil leaks, water intrusion, or obvious signs of wear. Regular visual inspection is crucial for identifying potential problems early.

Helpful Tips from Nautica Basile

* Quality First: Always opt for genuine BRP parts for greater reliability and long-term durability. Aftermarket parts may seem cheaper, but they often lead to future problems.
* Regular Inspection: Visually inspect the condition of the gaskets and oil seals at each service interval. Pay close attention to cracks, crazing, or signs of deterioration.
* Complete Replacement: If one component of the kit is worn, it is advisable to replace the entire kit to ensure a uniform seal and prevent future leaks.
* Proper Lubrication: Use marine-grade silicone grease when installing new O-rings and oil seals to facilitate installation and protect the components from corrosion.

Compatibility with my Evinrude/Johnson/OMC engine?

To ensure the kit's compatibility with your engine, always verify the part number in your engine's owner's manual. Alternatively, contact us providing the exact model and year of manufacture of your engine. Part numbers may vary depending on the year of manufacture and the specific model. Another option is to remove the old part and visually compare it with the product images on our website.

How often should I replace the lower unit oil seals?

The frequency of replacing the lower unit oil seals depends on the operating conditions. In general, it is recommended to replace them every 200 hours of operation or at least once a year, especially if you frequently navigate in saltwater. A periodic visual inspection can help identify any oil leaks and determine the need for replacement.

What type of grease should I use to lubricate O-rings and oil seals?

It is essential to use marine-grade silicone grease specifically for lubricating O-rings and oil seals. This type of grease is resistant to saltwater and prevents corrosion. Absolutely avoid the use of petroleum-based greases, as they can damage the rubber of the components.

What happens if I don't replace worn gaskets?

Failure to replace worn gaskets can lead to serious engine problems, including oil leaks, water intrusion, overheating, and, in the worst-case scenario, irreparable engine damage. Preventative maintenance is essential to avoid costly future repairs.
