How to Service Marine Lower Units to Prevent Water Damage
How to Service Marine Lower Units to Prevent Water Damage with AMSOIL Marine Gear Lube
Maintaining a boat motor is crucial, especially for high-performance engines that can reach up to 600 horsepower. These powerful motors need robust protection to ensure longevity and peak performance. One critical aspect of maintenance is servicing the marine lower units, which are submerged in water and prone to wear and tear. Proper lubrication is key to preventing water damage and ensuring smooth operation. AMSOIL Marine Gear Lube is an excellent choice for this purpose.
Understanding the Lower Unit
The lower unit of a boat motor is a complex assembly that includes the drive shaft, propeller shaft, bearings, gears, and seals. The drive shaft transmits power from the engine to the propeller shaft, which then spins the propeller at high RPMs. This entire mechanism operates underwater, making it vulnerable to water ingress and damage.
Step-by-Step Guide to Servicing the Lower Unit
1. Gather Necessary Tools and Supplies
Before starting, ensure you have all the necessary tools and supplies:
- AMSOIL Marine Gear Lube
- Screwdriver or appropriate tool for removing the plugs
- A container to catch the old gear lube
- Replacement plugs (if necessary)
- Gear lube pump or AMSOIL Easy-Pack
2. Draining the Old Gear Lube
To start, remove the top plug to release any pressure. Next, remove the bottom plug to allow the old gear lube to drain completely into your container. Removing the top plug first prevents a vacuum from forming and ensures smooth draining.
3. Inspect for Water Contamination
Once the old gear lube is drained, inspect it for signs of water contamination. Water-contaminated gear lube will appear milky. If you notice significant water contamination, further inspection of the seals and components may be necessary.
4. Refilling with AMSOIL Marine Gear Lube
After draining the old lube, replace one of the top plugs to create a seal. Then, use the AMSOIL Easy-Pack or a gear lube pump to fill the lower unit from the bottom plug. This method ensures there are no air pockets, providing complete lubrication. Fill until the new lube starts to overflow from the top plug hole.
5. Replacing the Plugs
Once filled, replace both the bottom and top plugs securely. Ensure that the plugs are tight and there are no leaks.

Why Proper Lubrication is Essential
Operating in a marine environment exposes the lower unit to water and contaminants such as fishing line, which can get tangled in the output shaft seal. This can lead to water ingress, which, if unchecked, can cause significant damage. Proper lubrication ensures that even if water enters the system, the gears and bearings remain protected.
The Role of AMSOIL Marine Gear Lube
AMSOIL Marine Gear Lube is specially formulated to provide exceptional protection for marine lower units. It can handle up to 15% water contamination without compromising its lubricating properties. This is crucial because water can enter the lower unit unnoticed, especially when the boat is in use. AMSOIL Marine Gear Lube ensures that the gears and bearings remain protected, even in challenging conditions.
The Benefits of AMSOIL Easy-Pack
The AMSOIL Easy-Pack is a game-changer in marine maintenance. Its design allows for easy and mess-free application. The flexible pack can be squeezed and rolled to ensure every drop of lube is used, and it can be threaded directly into the lower unit, eliminating the need for a separate pump. For those who prefer traditional methods, AMSOIL also offers a hard case with a pump option.
Common Issues and How AMSOIL Marine Gear Lube Addresses Them
1. Water Ingestion
Water ingestion is a common issue in marine lower units. AMSOIL Marine Gear Lube's ability to protect up to 15% water contamination ensures that even if water enters the system, the lubrication remains effective.
2. Fishing Line Damage
Fishing lines can get tangled in the output shaft seal, leading to leaks. AMSOIL Marine Gear Lube provides excellent protection and helps minimize the damage caused by such incidents.
Regular Maintenance is Key
To keep your boat motor in top condition, regular maintenance is crucial. Checking and replacing the gear lube as per the manufacturer's specifications will ensure smooth operation and extend the life of your motor. Always refer to your service manual for specific guidelines and intervals.
