Sierra 18-99524 Gearcase Filler 3 Gallon Gear Lube Filler Tank

The Sierra 18-99524 gearcase filler is a 3-gallon gear lube filler tank. It is also called a gearcase lubricant filler or lower unit gear oil filler. It is built to fill most outboard and sterndrive gearcases quickly and with less mess.

Key Features:

• 3-gallon capacity
• Translucent plastic body lets you check the oil level in the tank
• Tear-drop design resists tipping over
• Drip tray helps prevent messes
• Manual pressure relief valve
• Includes an E-Z Fill check valve and a hose assembly
• The check valve venting system creates an air-lock. This lets you remove the filler nozzle without losing much lubricant before the drain plug is replaced.
• Includes gearcase adapters for most Chrysler, Force, Evinrude, Johnson, Mercury and Mariner outboards, plus fitting adapters for Suzuki, Tohatsu, Volvo Penta and Yamaha

The Bravo and Verado gearcase hose fill adapter is sold separately.
