Skeg Guard for Mercury, Honda, Tohatsu/Nissan & Force 40-140HP – JLM0066 (Replaces 27071)

Skeg Guard for Select 40–140HP Outboards

The JLM Marine model JLM0066 is a stainless steel, bolt-on skeg protector for the engine and drive applications identified by the reference checks below. It fits over the skeg below the lower unit to help limit wear. A damaged skeg must retain enough sound material to support the guard and its mounting hardware.

Check Before Ordering

Match the brand, horsepower, model, gearcase, year and every restriction in the application table. Engines with the same horsepower can use different lower units. Confirm the actual skeg profile before ordering.

Fitment Table

The applications below follow JLM Marine's current application list. Each row applies only to the model details and years shown; do not extend a listed year range to later models.

Not listed? Send us your engine model, year and a photo of your gearcase before ordering.

Construction & Package

The model JLM0066 product photograph is marked “Marine Grade SS316.” The guard has a polished stainless steel finish and mounting holes. The matching kit photograph shows one guard, mounting fasteners, two Allen wrenches and a drill bit. Check the supplied hardware and instructions before installation.

Before Installation

• Keep the engine off and the boat secure. Follow the engine and kit instructions.
• Check the guard profile, seating and mounting position before drilling. Do not force a mismatched guard into place.
• Use the drilling size, fasteners and tightening procedure specified for the actual kit; generic instructions may not apply.
• Do not install on a cracked gearcase or a skeg with insufficient sound material. Ask a qualified marine technician if damage or fit is uncertain.

This guard does not guarantee protection from collisions, restore a structurally damaged lower unit or guarantee improved steering or speed.
