Make sure to regularly check for any artifacts of corrosion, such as cracking, fissures, or pitting, and remove any obstructions that might be impacting the overall performance of your outboard.

Store in a Proper Environment

When you’re done using your lower unit, store it in a dry, enclosed place away from extreme temperatures. Keeping your lower unit in a cold, damp environment can do more harm than good if not properly taken care of.

Be Wary of Overheating

Overheating is the number one cause of premature wear and tear on outboard lower units, so keeping an eye on the temperatures is essential. If a temperature gauge is available, monitor the heat levels and shut off the engine if it gets too high. If no temperature gauge is available, keep the RPMs low and avoid long, hard runs.

Use Protective Coatings

Protecting the outside of the outboard motor should be a priority, as dirt, grime, and other pollutants can quickly deteriorate the engine. Invest in a protective coating that creates a barrier between these contaminants and the outboard motor – this will help extend the lifespan of your lower unit.

Utilize Outboard Couplers

Using couplers between your outboard and the propeller shaft can help keep a firm grip on your propeller while providing an extra layer of protection against wear and tear. In critical situations, couplers will act as a buffer, preventing significant damage.

Change your Lower Unit Oil

Regularly changing your lower unit oil helps to ensure a longer life and more performance. This is important, however, as the oil plays a vital role in the life of outboard motors, combating sludge and scum buildup resulting from normal wear and tear.

Clean the Lower Unit

Cleaning your sei lower units are relatively simple and doesn’t take too much time. Regularly removing all the dirt and debris that accumulates on the unit and its components is a surefire way to extend the life of your motor and give it the care it needs to operate optimally.

By following the tips mentioned above, you should have no problem prolonging the life of your outboard lower unit. Enjoy the freedom and flexibility it offers, and make sure you take the necessary steps to ensure longevity.

Final thoughts

Maintaining a healthy lower unit on your outboard engine is essential to keep your vessel running smoothly and safely. With regular inspections, timely oil changes, and thorough flushing, you can optimize the longevity and performance of your outboard. By being proactive and carefully following these steps, you can ensure your lower unit stays in tip-top condition – providing you with years of worry-free sailing and mechanized fishing. So, don your hat and gloves and get to work! It’s time to give your lower unit the TLC it needs.
