Ez-Steer complete system for sale. This came off of my 19' Arima with Honda 150 and Merc 8 kicker and it worked great. From what I can tell this is the Outboard to Outboard Long Kit (spec says 29 to 50", my measurements are more like 32-54" from end to end).

For reference: EZ Steer 60003 | Fisheries Supply

See pics for more detail. I haven't seen this type of main bracket anywhere but it seems like it would work just fine with my Suzuki 140.

Asking $200 $150. I'll consider shipping on buyer's dime but this may take 2 boxes due to the long tube.
