Questions & Answers
Is this a genuine original part?
This is a genuine Ultraflex product, manufactured in Italy. It is the industry standard for aftermarket side-mount controls and meets or exceeds all OEM specifications.
How do I know if it is compatible?
Compatibility is determined by your control cables. This unit fits standard 33C/universal cables (C2/C8) directly. For specific engine brands like Mercury or Yamaha using proprietary cables, an adapter kit (like the K35) may be required.
Can I install this on the port side of my boat?
Yes, the B184 is designed to be fully reversible. It can be mounted on either the starboard or port side, and either horizontally or vertically depending on your dash configuration.
Note: Please verify your existing cable type and space requirements before purchasing. Neutral safety switch X12 is sold separately unless otherwise stated.
