Description
DOMETIC SEASTAR Single Engine Adapter Plate for Mercury 1995 and Newer – HO5035
The Dometic SeaStar HO5035 is a single-engine adapter plate used in selected SeaStar outboard steering installations for Mercury engines from 1995 and newer, where an adapter is required to achieve the correct steering cylinder geometry and mounting alignment.
Adapter plates are fitment-specific steering hardware. Before installation, confirm the engine model, year, steering cylinder, and SeaStar application guide requirements. Do not substitute adapter hardware unless the manufacturer application chart confirms compatibility.
- Application-specific adapter plate for selected Mercury single-engine installations.
- Supports proper SeaStar steering cylinder alignment where the engine bracket geometry requires an adapter.
- Used during hydraulic steering installation or refit rather than as a universal service part.
- Helps maintain correct steering travel and linkage geometry when matched to the proper engine/cylinder combination.
