The transom assembly is the least discussed component but inarguably, one of the most important. This holds true for every MerCruiser sterndrive application. 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.
When you consider the importance and value of this critical component, make sure to also 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.
This transom assembly comes with a Mercruiser diesel sticker although it is interchangable between gas and diesel.
