MerCruiser Gear Lube Monitor Bottles

MerCruiser Gear Lube Monitor Bottles

Proper lubrication of your Mercruiser engine’s gears is crucial for efficient performance on the water. A MerCruiser gear lube monitor bottle helps lubricate the transmission gears and prevents wear and heat damage to the critical internal components of your boat’s engine system. The Mercruiser gear lube reservoir bottle allows easy monitoring of gear lube oil quantity to ensure that the level isn’t dropping too rapidly. If the gear lube is dropping sharply, you should check your fuel system and make sure all the Mercruiser engine parts are working well.

Your Mercruiser gear lube bottle operates in a high heat environment because it is right next to the engine. Over time, the heat from the engine causes oil to expand in the plastic bottle, which may puncture and damage the gear lube monitor bottle. All these factors, plus aging, cause the gear lube monitor bottle to become brittle and potentially leak gear lube into your water distribution system. Routine replacement is necessary to keep your engine performing smoothly and efficiently.

MerCruiser Gear Lube Bottle

NuWave Marine recommends regularly checking your Mercruiser drive lube bottle and changing the gear oil at least once a year. Once you’ve removed the old transmission fluid, take a good look at the old fluid before pumping in the new fluid. The transmission fluid should be translucent, reddish, and have little to no odor. If the fluid has a thick and milky appearance, particulates, or a burnt smell, your Mercruiser engine is telling you something is wrong. 

You’ll need to replace the Mercruiser drive lube bottle if it is punctured and leaking oil onto your engine. Make sure your boat is in a level position before changing the gear lube monitor bottle. Most boats leak drive oil because the hose on the lube monitor bottle is faulty. A leaky hose may spill significant amounts of drive oil into your engine, causing damage to the ignition system and spark plug.
