What to Compare Before Buying
- Check that the boat uses a standard 1-1/4-inch drain plug. The stated replacement fit does not establish compatibility with every opening or plug design.
- Confirm that the inside-transom mounting arrangement matches the boat’s existing installation.
- Follow the boat and plug manufacturer’s instructions for installation and checking the seal.
Before You Decide
Confirm the plug size, mounting arrangement and part number for the replacement you need. The listing describes the plug as forming a watertight seal, but fit and installation matter; that description is not a guarantee for a particular boat.
