If you have a lot of wear and tear on your rudder this is a simple replacement. Just unscrew your existing motor and re-install on this rudder and you will be ready to go.
The Motor Mount may be needed if going from Mako to Marlin, or if current mount is damaged.
*If you are converting from a Manta make sure your motor cable is long enough. Older Manta motors do not have a long enough cable for the conversion so confirm cable length is at least 7.5 feet prior to ordering for conversion*
