The KeelGuard is a very simple product to install; however, the instructions must be strictly followed. Any short cuts or missed steps will jeopardize and compromise the full bonding capabilities of the 3M adhesive. Average installation time is 60-90 minutes depending on the length of the KeelGuard.
Each kit has everything needed for a professional installation except the cleaning agent (isopropyl alcohol or acetone) used in step 2.
For best results 3M recommends the adhesive should not be applied when temperatures are below 18C. This specifically applies to the temperature of the boat hull, not necessarily the ambient air temperature. If the boat is stored outside in cooler weather, we recommend bringing it into a warm shop or garage and leaving it overnight, giving the boat sufficient time to rise to an acceptable temperature. It is important that the KeelGuard and the boat hull are at the same temperature during the application process.
Typically, the KeelGuard is mounted 4 to 6 inches above the waterline on the bow, ending 2 to 3 feet or more beyond the lowest point of the Keel.
For personal watercraft, begin the KeelGuard approximately 1 inch below the bow hook, running the length of the keel, and ending 4 to 6 inches forward of the pump intake.

A keel protector is NOT recommended in the following applications:
- if your trailer is designed with the boat resting on center rollers or a support beam along the keel. If the rollers can be lowered or the side bunks raised to clear the roller, the KeelGuard adhesive bond will not be compromised.
- on aluminum boats designed with a raised reinforced center rib, large rivets, or any hull design where a full surface bond is unachievable.
- on hulls with a non-standard V-shape or with aggressive complex angles found on some canoes, kayaks, pontoons, catamarans, and some modern personal watercrafts.
- on vessels made from LSE (low surface energy) plastics, such as polypropylene and polyethylene (kayaks, canoes and some PWC's).
- on boats using floating docks where the entire weight of the boat rests on the keel or where the rear of the guard could snag during launching.
