ALL BILLET BRACKETS ARE NOT CREATED EQUAL!
The Hardin Marine bracket not only has a unique mounting feature, they also have an integrated O-ring cushion. It will not scratch or mar the cooler and it provides a non-slip clamp. Inferior brackets literally crush your cooler to hold it. Don't crush your cooler - clamp it correctly with Hardin Marine oil cooler clamps!

On boats equipped with MerCruiserŽ Bravo Stern Drives the rear engine mounts are incorporated into the engines flywheel housing.  Therefore the option of using a flywheel housing with a built-in cooler is not possible.  To address this situation and external cooler is mounted on top and across the back of the engine with special brackets bolted to the flywheel housing.  Hardin Marine offers a 3" diameter cooler that flows more volume than a stock cooler and attaches to the flywheel housing with 2 billet aluminum windowed brackets that have an internal O-ring that when clamped down prevents galling the cooler and helps to cushion and shock mount the cooler.  Not only are theses brackets functional but they are very attractive with their black anodized finish.
