OMC STARTER MPN-18-5911

Protect the integrity of your marine lower unit with the MRC Upper Gearcase Seal (MFG Number: 18-2648). This critical seal is designed to prevent water intrusion and lubricant leakage from the upper section of your boat's gearcase. A compromised seal can lead to significant internal damage, including corrosion and wear on critical gears and bearings, ultimately resulting in costly repairs and potential failure of the lower unit. Ensuring a watertight and properly lubricated environment is paramount for the longevity and performance of your marine propulsion system.

• Key Features
• Superior Sealing Performance: Engineered to create a robust barrier against water and contaminants.
• Prevents Lubricant Loss: Effectively seals in essential gear oil, maintaining proper lubrication.
• Critical Protection: Safeguards expensive internal components of the upper gearcase from damage.

The MRC Upper Gearcase Seal plays a vital role in maintaining the operational efficiency and durability of your boat's lower unit. It acts as the first line of defense, preventing the ingress of water, which can emulsify with gear oil, reducing its lubricating properties and accelerating wear. Furthermore, it ensures that the specialized gear oil remains contained, providing the necessary protection for gears, bearings, and shafts operating under high stress. This seal is a small component that provides immense value in preventing major mechanical failures.

Application of this seal is crucial during routine maintenance or when replacing internal components of the lower unit. Marine environments are inherently harsh, with constant exposure to saltwater or freshwater, which can accelerate corrosion and material degradation. The MRC Upper Gearcase Seal is manufactured to withstand these challenging conditions, offering long-lasting protection and reliable performance. By investing in a quality upper gearcase seal, you are proactively protecting your marine drivetrain from the damaging effects of water and ensuring smooth, efficient operation of your boat.
