Motor Mounts - Rear Offshore Mounts

Billet Aluminum Front Single Engine Mount
Your Price:
$329.99

Billet Aluminum Rear Side by Side Engine Mount

625-8828

In the world of professional offshore powerboat racing the top teams are always looking for ways to save weight without sacrificing performance and durability Hardin Marine knows there is no better way to test a product than to expose it to the abuses and demands of full blown racing While tested in extreme conditions these mounts are still right at home in a recreational pleasure boat. 

While bearing the same nominal measurements as the factory Mercury Racing engine mounts that’s where the similarities end. These engine mounts are CNC machined from aero space grade  6061-T6 billet aluminum. Front mounts feature our exclusive billet engine block mounting pads. These pads form a structural bridge like connection to the base of the engine mount. They also provide for an optional speedy engine removal option while the base mount stays in the boat.Next the mounts are machined to accept precision stainless steel bushings in the mounting hole locations to ensure a secure fit and prevent premature wear. After construction of the mounts they are then black hard coat anodized for corrosion resistance and long life.

So if your looking for the strongest and lightest engine mount option (half the weight of conventional steel mounts) then there is no better choice than these mounts.  Available in 4 configurations, the shipping mounts are commonly used in catamaran hulls, while the staggered or side by side mounts are perfect for vee bottom installations.  

NOTE: THESE ARE RAW FINISH
