Did you know that Bonzi mounts are CNC machined from solid extrusion, not stamped or bent from flat material, creating unnecessary weak joints, unlike other weak “bent” mounts that are on the market? Why would you ever want to sacrifice quality and strength for your boat?
Be sure to add a bottle of Bonzi Break-in Oil – it is formulated to get the max performance out of your stock or modified engine by properly seating the ring to the cylinder through what is known as a scuffing process.
Most 100% synthetic oils are so slick that they do not allow this process or take an extremely long time to do so.
With just mixed 5 ounces to a gallon, it allows for complete break-in in just one gallon.
