Genuine OEM Mercury / Quicksilver Gear Lube Monitor Reservoir Cap (Part # 36-8067271)

Maintain proper fluid pressure and protect your outdrive with the Genuine OEM Mercury / Quicksilver Gear Lube Monitor Reservoir Cap (Part # 36-8067271). Designed specifically for the drive oil lube bottle mounted inside the engine compartment, this factory replacement cap provides a tight, leak-free seal that keeps drive lubricant contained while preventing moisture, dirt, and airborne debris from contaminating your drive system.

Over time, engine bay heat cycles and exposure to oil vapors can cause plastic bottle caps to warp, crack, or lose their sealing tension. Replacing a worn cap is a quick, tool-free maintenance step that ensures your gear lube monitor functions properly and protects your upper and lower units from costly damage
