If your boat's engine is under warranty we recommend this flapper option so as to not inadvertently void the warranty (some warranties require a properly functioning flapper).

You may also choose this flapper option for peace of mind. There is no performance change with the replacement flapper installed.

The 3M 5200 Marine Adhesive comes in two versions.

Slow Cure - takes a week to cure. It is significantly stronger than the fast cure and exceeds the industry standard.

Otherwise they apply and clean up the same. On both, the boat must remain still and above 40 degrees Fahrenheit or 5 degrees Celsius while curing.

You will also need masking tape and rags.
