Most people’s repower focus is on the engine and sterndrive. However, the transom delivers the cooling water, manages the exhaust, serves as the primary engine mount, controls the steering, manages the trim system, delivers MerCathode corrosion protection and serves as the conduit for speed and trim control. The transom also serves the important function of sealing seawater outside the boat.
The transom assembly is the least discussed component but inarguably one of the most important. When you consider the importance and value of this critical component make sure to consider the condition of your present transom assembly. Taking care of a transom during a repower may save from lost time on the water later.
In many cases it is more economical to replace the transom assembly rather than repair it.
