Easy and smooth


Easy to install, operated smoothly. Appears to be a quality engine control.



Ordered the shifter and new cables at the same time they shipped and I received them in a couple days very quick. Have them installed but have not put the boat in the water as of yet. I would buy from this company again very satisfied.


Can the CHX8555P control be configured to mount on port (left) side of boat?

Unfortunately, according to Dometic/SeaStar Solutions, the CHX8555P engine control is only for starboard (right) mounting.
