Best Mercury Outboard Foot Grease For Smooth Sailing

When it comes to keeping your Mercury outboard motor in top shape, one thing you might not think about regularly is the foot grease, also known as propeller shaft grease or water pump grease. But trust me, it's crucial for ensuring your boat operates smoothly on the water. In this comprehensive guide, we'll delve into the best Mercury outboard foot grease options available, discuss why it's important, how to apply it, and share some pro tips to keep your motor running like a dream.

Why Mercury Outboard Foot Grease Matters

Mercury outboard motors are synonymous with quality and reliability in the boating world. These motors face tough conditions like saltwater, high speeds, and extreme pressure. Here's where foot grease plays a pivotal role:

• Reduces Friction: A specialized grease reduces wear and tear by creating a barrier between moving parts, especially in the lower unit where gears and propeller shafts interact.

• Protects Against Corrosion: It acts as a shield, defending metal components against the corrosive effects of water, particularly saltwater.

• Improves Performance: With smoother operation, your motor doesn't have to work as hard, potentially leading to better fuel efficiency and less chance of overheating.

Top Choices for Mercury Outboard Foot Grease

1. Mercury Marine Quicksilver 2-4-C Grease

• Type: Lithium-based, water-resistant marine grease.
• Benefits: Excellent water resistance, protects against rust, oxidation, and water washout.
• Where to Use: Water pump bearings, propeller shafts, steering cables, and other water-exposed parts.

2. Lucas Oil Marine Grease

• Type: Multi-purpose grease with unique polymer chemistry for superior water resistance.
• Benefits: Exceptional adhesion, reduces noise, and prevents rust and corrosion.
• Where to Use: Gears, bearings, water pump seals, and any moving parts in the lower unit.

3. 3M 08877 Marine Silicone Sealant and Lubricant

• Type: Silicone-based lubricant.
• Benefits: Excellent for sealing and lubricating in harsh marine environments.
• Where to Use: Seals, gaskets, and as a water-repellent lubricant for various applications.

4. Stabil Marine Grease

• Type: High-performance, extreme pressure marine grease.
• Benefits: Superior water resistance, prevents rust and corrosion, and can withstand high temperatures and pressures.
• Where to Use: Ideal for lower unit gears, propellers, and steering mechanisms.

How to Apply Mercury Outboard Foot Grease

Applying grease correctly is as important as choosing the right product. Here's a step-by-step guide:

1. Gather Your Tools: You'll need the grease, a clean cloth, a propeller wrench, a grease gun, and gloves.

2. Clean the Area:

   • Before applying grease, thoroughly clean the areas you'll be working on. Use a marine degreaser if needed to remove old grease and grime.

3. Inspect and Lubricate:

   • Remove the propeller. Apply grease to the propeller shaft, ensuring the entire shaft is covered.
   • For the water pump, after removing the old pump, grease the bearing housing and any metal components before reassembling.

4. Assembly:

   • Apply the appropriate grease to each part before putting them back together.
   • When reinstalling the propeller, add a little more grease for extra lubrication and sealing.

5. Check and Adjust:

   • After reassembly, ensure everything spins freely without resistance. If not, some grease might need to be removed.

   <p class="pro-note">🌟 Pro Tip: Always grease the propeller shaft immediately after each use, especially if you've been in saltwater, to prevent corrosion and rust.</p>

Common Mistakes to Avoid

• Over-Greasing: Too much grease can cause pressure buildup, leading to seal leaks and reduced motor efficiency.

• Under-Greasing: Not enough grease can result in parts wearing out faster due to increased friction.

• Using the Wrong Grease: Not all greases are created equal. Using automotive grease on a marine motor can lead to suboptimal results due to poor water resistance.
