Keel Guard 27021 SkegGuard Stainless Steel Skeg Protector & Repair Guard for MerCruiser Alpha 1

The Megaware KeelGuard SkegGuard (MPN: 27021) is a dual-purpose marine skeg protector and skeg repair solution engineered for MerCruiser Alpha 1 stern drives. Whether you're looking to prevent skeg damage before it happens or restore an already damaged lower unit, this stainless steel guard delivers a cost-effective, do-it-yourself fix that can save hundreds of dollars over professional welding or lower unit replacement.

Built from 18-gauge, mirror-polished marine-grade 316 stainless steel, the SkegGuard slides over your existing skeg and conforms precisely to your lower unit, ensuring no discernible drag or loss of performance on the water. The guard's profile is engineered to fit flush, maintaining your drive's hydrodynamics while providing a tough outer shell.

Key Features:

• 18-gauge marine-grade 316 stainless steel construction with a mirror-polished finish for lasting corrosion resistance and appearance
• 3mm thickened reinforced lower wear tab across the bottom — the most vulnerable area — guards against ramp dragging, rocks, submerged debris, and river running
• Drain hole on the bottom prevents water from collecting, eliminating stagnation, corrosion, and freeze damage
• Installs with as little as 2–3 inches of skeg remaining — works even on heavily damaged skegs
• DIY installation in under 10 minutes using common hand tools — no welding required
• Includes self-locking mounting hardware and hex wrenches
• 3-year manufacturer's warranty from date of purchase (retain receipt)

The SkegGuard secures with self-locking hardware, eliminating concerns about loosening over time. Installation involves sliding the guard over the skeg, tapping it into place with a rubber mallet, and securing it through pre-drilled holes with a standard 1/4-inch drill bit — a straightforward process requiring no special skills or equipment.
