For outboard motors and other marine applications, it’s crucial to use a sealant that maintains corrosion resistance and withstands the marine environment. We recommend:
- Marine-grade silicone: This creates a flexible and waterproof seal, preventing moisture penetration.
- Marine polyurethane: Known for its durability and adhesion strength, it is suitable for sealing bolts that face continuous exposure to saltwater.
Both options help protect the fasteners from corrosion and secure the integrity of the bolted connection.
