  • Universal Fit: Designed for broad compatibility across a wide range of marine engines
  • OEM Quality: Engineered to meet or exceed original equipment specifications

Installation Note: Pipe sealant with Teflon is recommended for use on plug threads to ensure a proper seal and prevent leaks.

Fast Shipping and the lowest price on the Husky Floor Liners. I searched all the internet and this place had the best price. Shipping was not free but it was still cheaper than anywhere else with free shipping at those sites.
