I need a little help please.
I am trying to set up controls and steering on my 25 hp Mariner. The best I can tell it is a late 80s or early 90s model year. It has nothing coming out of the control area on the side of the motor so I assume I must need some type of linkage kit.
Can you please direct me to everything I need to get this working?

You need to find a serial number, the older Mariners were Yamaha's and if you can find a serial number you can tell when it was made and then look for parts either from Mariner or Yamaha
