Detailed FAQ Section
How do I know if I need to replace my Mercruiser Gen II transom assembly?
The most common signs include water entering the bilge, excessive engine vibration, or visible corrosion on the gimbal housing. You might also notice difficulty trimming or shifting. These issues suggest that the internal components of your Gen II transom are failing. A thorough inspection of the bellows, seals, bearings, and housing can confirm if replacement is necessary.

Can I install the Gen II transom assembly myself?
Yes, if you have mechanical experience and access to the right tools, it’s possible. The process involves removing the old assembly, cleaning the mounting surface, and installing the new unit with care.

If unsure, hire a certified marine technician to ensure correct installation and warranty compliance.
