Designed for durability, efficiency, and easy installation, this skeg guard not only protects your lower unit but also saves you from costly repairs caused by underwater collisions or abrasive wear.
This blog explores everything about skeg guards tailored for SEI 106 and 108 lower units, offering actionable advice, maintenance tips, expert recommendations, and a detailed FAQ section to help you make the best decision for your boat.
Overview / What Is Skeg Guard for SEI 106 and 108 Lower Units?
A skeg guard is a protective metal or composite sleeve that encases the original skeg on your outboard or sterndrive engine. For SEI 106 and 108 models — which are Mercruiser-compatible lower units — the guard serves as a shield against rock strikes, sandy shallows, trailer mishaps, and other common marine hazards.
Crafted from marine-grade stainless steel or aluminum, skeg guards not only prevent further skeg damage but also restore a chipped or bent skeg’s hydrodynamic profile, improving steering control and fuel efficiency. These guards are precision-fitted for SEI models to ensure a tight, vibration-free installation.
Top Benefits of Installing a Skeg Guard
Installing a skeg guard on your SEI 106 or 108 lower unit is a proactive investment. Here are the top advantages:
- Protection: Shields the skeg from impact damage.
- Hydrodynamic Integrity: Improves water flow and steering response.
- Cost Savings: Prevents costly replacements and repairs.
- Resale Value: Maintains your lower unit’s condition for future sale.
- Quick Installation: Usually installs in under 30 minutes with basic tools.
How to Install a Skeg Guard on SEI Lower Units
Knowing how to install a skeg guard on your SEI 106 or 108 lower unit will help you protect your gear without professional help. Follow these steps:
- Clean and dry the existing skeg surface to remove any debris or corrosion.
- Slide the skeg guard over the existing skeg and align it properly.
- Drill pilot holes for the included locking screws if required (some models are bolt-free).
- Tighten the screws to secure the skeg guard firmly in place.
Always follow manufacturer instructions for best results. A properly installed guard should not rattle or shift during operation.
Common Issues and Troubleshooting Skeg Guard Installation
Even though installation is straightforward, you might encounter a few challenges:
- Improper Fit: Ensure you’ve selected a skeg guard made specifically for SEI 106 or 108 units. A universal model may not offer a secure fit.
- Rattling or Vibration: If the guard isn’t aligned properly or screws are loose, vibrations can damage your unit.
- Corrosion Risk: Marine-grade stainless guards are corrosion-resistant, but ensure no moisture is trapped during installation.
If you’re unsure, consult your dealer or a marine technician for professional installation advice.

Detailed FAQ Section
How does a skeg guard enhance performance?
While a skeg guard’s primary role is protection, it also helps maintain a consistent hydrodynamic shape at the lower end of your engine. This improves water flow around the propeller, which leads to better steering control and fuel efficiency. If your original skeg is bent or chipped, a skeg guard restores its streamlined profile without needing full replacement.
Is a skeg guard a permanent solution?
No, a skeg guard is considered a semi-permanent accessory. It’s designed to be removable yet durable enough to last for years. It serves both as a protective shell and a way to avoid costly skeg repairs. If removed, the guard typically leaves the original skeg untouched unless corrosion has occurred underneath. If properly maintained, most skeg guards last 5–10 years.
Will the skeg guard fit if my skeg is damaged?
Yes, most skeg guards are designed to accommodate minor damage like chips or small bends. However, if the skeg is severely broken or missing large portions, installation may not be possible without repair. Always verify compatibility before purchase. Our model is custom-engineered for SEI 106 and 108, so it generally fits well even on slightly worn skegs.
Can I install a skeg guard myself, or do I need a pro?
Yes, most boat owners can install a skeg guard in under 30 minutes with basic hand tools. The process involves cleaning the original skeg, aligning the guard, and tightening set screws. Clear instructions are included with your purchase. However, if you’re unsure or uncomfortable with DIY, a marine mechanic can easily install it during your next service appointment.
Is the skeg guard compatible with saltwater environments?
Absolutely. The Skeg Guard for SEI 106 and 108 is made from marine-grade stainless steel, which offers excellent corrosion resistance in saltwater. To further protect it, rinse your lower unit after each saltwater outing and consider applying a light anti-corrosion coating during offseason storage. Proper care ensures long-lasting performance even in briny conditions.
Conclusion
The Skeg Guard for SEI 106 and 108 Lower Units for marine is more than a protective accessory — it’s a smart investment in your boat’s longevity and performance. It enhances fuel efficiency, restores damaged skegs, and minimizes the risk of expensive repairs. Whether you cruise freshwater lakes or saltwater coasts, this skeg guard delivers reliable protection for years to come. Install it once, and gain peace of mind every time you hit the water.
