Quicksilver Gear Lube Bottle 8M0075710 — Direct-Fit MerCruiser Alpha & Bravo 2002+ OEM-Style Replacement Reservoir

Quicksilver 8M0075710 is a direct-fit replacement gear lube reservoir bottle designed for select MerCruiser Alpha and Bravo sterndrives (2002 and newer) to restore proper gear lube containment and serviceability.

This replacement reservoir is built to the original Mercury Marine specifications and fits MerCruiser Alpha and Bravo sterndrives with standard cooling introduced in 2002 and later. It provides a factory-compatible container for gear lube where the original bottle has been cracked, warped, or lost during maintenance. The unit is engineered for straightforward installation with common shop tools; note that installation hardware and the gear lube hose are not included, so those are sourced separately during service.

Will this bottle fit my MerCruiser Alpha or Bravo sterndrive?

If your sterndrive is an Alpha or Bravo model year 2002 or newer with standard cooling, this Quicksilver reservoir is intended as a compatible replacement. Fitment follows Mercury Marine OEM design so mounting points and fill orientation match the original equipment in applicable drives.

• Compatible with MerCruiser Alpha and Bravo sterndrives (model year 2002+ with standard cooling)
• Designed to match factory mounting locations and hose routing
• Replaces damaged, cracked, or missing gear lube bottles

How do I install the Quicksilver 8M0075710 gear lube bottle?

Installation is intended to be simple for anyone familiar with basic marine service and common hand tools. Remove the old reservoir, transfer or replace clamps and hoses as needed, and secure the new bottle to the original mounting points. Because the product ships without mounting hardware or hose, have the appropriate clamps and any specific bolts on hand before beginning.

• Requires common shop tools—screwdrivers, pliers, and socket set
• Mounts to factory bracket locations; check existing bolts and grommets
• Hose and installation hardware are not included—reuse or replace as necessary

What should I check after installing this replacement reservoir?

After installation, confirm the bottle is secure, all hose connections are tight, and there are no leaks when the system is filled with gear lube. Run the engine briefly and inspect for seepage around hose fittings and mounting points. Verify fill level and top off to the manufacturer-recommended specification for your sterndrive.

• Inspect for leaks at hose connections and bottle seams
• Ensure secure mounting to prevent vibration damage
• Refill gear lube to the sterndrive manufacturer’s recommended level
