Choosing The Right Grease For Your Boat's Outdrive

Grease is an essential part of boat maintenance, acting as a lubricant between moving parts and a moisture barrier to keep water out. When it comes to outdrives, there are a few types of grease that can be used. One option is a premium marine grease such as Quicksilver® 2-4-C, which is a versatile lithium-based grease that can withstand a wide range of temperatures and won't break down when mixed with water. Another option is a marine tube grease, which can be used to lubricate zerk-type grease fittings found on the outdrive. Additionally, for boats used in saltwater, a product like Merc's Special Lube 101 can provide extra protection for steering rods. It's important to consult the operation and maintenance manual for specific grease points and requirements, as these can vary depending on the make and model of the boat.

Grease for gimbal bearing

Grease is an essential lubricant for the moving parts of your boat and helps to keep water away from these parts. It is important to use the right grease for the job.

For the gimbal bearing, a dedicated marine grease is recommended. Quicksilver 2-4-C Marine Grease is a popular choice and is suitable for use on both inboard and outboard motors. It is a lithium-based grease that can be mixed with water and is oxidation-resistant. It also has extreme pressure additives that make it suitable for a wide range of applications and temperatures.

Other greases that can be used for the gimbal bearing include:

• Quicksilver Gimbal Bearing and U-Joint Grease
• Volvo Penta High-Quality Number #2 Wheel Bearing Grease
• Marine Wheel Bearing Grease (blue-coloured)
• Amsoil Synthetic Marine Grease
• Yamaha Blue Grease
• White Lithium Grease
• Valvoline Red Grease for European Vehicles
• Lubriplate High-Temp Water-Resistant Grease

It is important to note that some greases are not suitable for the gimbal bearing. For example, some sources advise against using grease with graphite or Teflon, as it can cause the bearing to stop spinning and lead to wear and tear. It is also important to grease the gimbal bearing regularly, at least once a year, to maintain its condition.

Marine grease vs. regular grease

Marine grease and regular grease are both composed of the same three basic components: a base oil, a thickener, and additives. However, the thickeners used in marine grease are typically water-resistant, such as anhydrous calcium, aluminum complex, or lithium complex. This gives marine grease its superior water-resistant properties compared to regular grease. Marine grease also contains additives to boost corrosion resistance, which is especially important in marine applications where exposure to water is common.

The choice between marine grease and regular grease depends on the specific application and requirements. Regular grease is readily available, affordable, and suitable for a wide range of applications. It is a good choice for general-purpose lubrication and maintenance. However, regular grease may not be suitable for specialised applications, such as marine environments, where it can wash away easily, leaving components vulnerable to corrosion and damage.

On the other hand, marine grease is specifically designed for high-moisture environments. It stays in place once applied and provides enhanced protection against water and corrosion. This makes it ideal for marine applications, where equipment is frequently exposed to water. Marine grease also tends to be more durable and long-lasting, reducing the need for frequent reapplication. However, due to its specialised formulation, marine grease may be more expensive and less readily available than regular grease.

When choosing between marine grease and regular grease, it is important to consider the specific requirements of the application. Marine grease is the preferred option for marine equipment due to its water resistance and corrosion protection. Regular grease can be a cost-effective and versatile choice for general-purpose lubrication but may not provide sufficient protection in marine environments.

In summary, marine grease and regular grease serve similar purposes, but marine grease is specifically formulated for superior performance in wet and corrosive conditions. Its water-resistant properties and corrosion protection make it ideal for marine applications, ensuring equipment reliability and longevity. While regular grease is a versatile and affordable option, marine grease is the recommended choice for maintaining and protecting marine equipment.

Grease for steering rods

Grease is an essential part of boat maintenance, acting as a lubricant and moisture barrier for moving parts. It is important to use the right type of grease for your boat's steering rods to ensure optimal performance and protection.

For steering rods, it is recommended to use a premium marine grease such as Quicksilver 2-4-C. This type of grease is specifically designed for outboard motors and can withstand a wide range of temperatures and applications. It is also resistant to oxidation and degradation, making it a durable and reliable option.

When applying grease to steering rods, it is important to follow the manufacturer's instructions and recommendations. Consult your boat's operation and maintenance manual to identify specific grease points and the frequency of greasing required. Grease points on steering rods may include the steering cable and the steering link rod.

In addition to using the right grease, it is important to use the correct tools for application. A small grease gun that holds a 3-ounce grease cartridge is suitable for at-home maintenance. A flexible tube or hose attached to the gun outlet can make it easier to reach tight spaces and grease fittings. Ensure that you wipe off any old grease, dirt, or residue from the grease fitting before applying new grease to keep the tip of the grease gun clean and prevent debris from being pushed into the fitting.

By using the appropriate type of grease and following the recommended application techniques, you can help ensure the optimal performance and longevity of your boat's steering rods.

Grease for propeller shaft

Greasing the propeller shaft is an important maintenance procedure for boat owners. It helps prevent the propeller hub from corroding and seizing on the shaft. When reinstalling the propeller, it is good practice to coat the propeller shaft with clean grease.

Types of Grease

There are many different types of grease available for propeller shafts, but it is important to choose one that is suitable for marine use. Marine grease should be waterproof and able to withstand a wide range of temperatures. Here are some of the most commonly recommended greases for propeller shafts:

• Quicksilver 2-4-C Marine Grease: This is a high-quality, lithium-based grease that is versatile and can be used on a long list of components. It maintains its consistency without breaking down, even when mixed with water. It is available in an 8-ounce squeeze tube or a 14-ounce grease gun cartridge.
• Mercury 2-4-C Marine Lubricant: This grease is also suitable for propeller shafts and helps to prevent corrosion and seizing.
• BRP Triple Guard: This grease is recommended by some boat owners and has multiple uses on a boat.
• Yamaha Yamalube Marine Multi-Purpose Grease: This is an affordable option that can be easily obtained.
• White Lithium Grease: This grease can be used on propeller shafts, but it may react with salt water and cause issues.

Application

When applying grease to the propeller shaft, it is important to first wipe off all the old grease and inspect the shaft for any damage. If there is any fishing line or damage to visible seals, these should be removed or replaced. The threads and splines on the propeller shaft should also be cleaned and inspected for damage. If any issues are found, it is recommended to contact a marine service center for assistance. Once the propeller shaft is clean and in good condition, grease can be applied to all threads and splines before reinstalling the propeller and hub kit.

Grease for steering cable

Grease is an essential part of regular boat maintenance. It acts as a lubricant between moving parts and as a moisture barrier to keep water away from these parts.

There are a variety of greases available for boat steering cables. Some sources recommend using a premium marine grease, such as Quicksilver® 2-4-C, which is a versatile lithium-based grease that won't break down when mixed with water and offers excellent resistance to oxidation and degradation. It is specifically designed for use in a wide variety of applications and temperature ranges.

Other recommended greases include BRP Triple Guard Grease, which is great for most things on an outboard, and Evinrude or Yamaha blue grease, which can be used in combination with a steering guard nut.

It is important to note that some sources advise against using grease on steering cables, as it can cake up and bind the cable over time. Instead, they suggest using penetrating oil, silicone, or lithium grease. One user recommends using Mercury/Quicksilver 2-4-C grease because, while it is a type of lithium grease, it is less viscous than other options and flows better.

Additionally, it is recommended to clean and lubricate the steering rod regularly, regardless of the type of grease used. This can be done by turning the motor to wipe and regrease the rod without fully removing the cable.

Before applying any grease, be sure to consult your boat's operation and maintenance manual to verify the specific grease points and requirements for your model.
