Technical 50 Mercury Heater Cable Help

Discussion in 'The Hokey Ass Message Board' started by Glenny, Nov 15, 2018.

  1. Hoping someone can help.
    I'm wondering if anyone has a shop manual diagram showing the routing and location of the heater/fresh air control cables in a 50 Merc .
    I have all the cables, the heater and dash controls are all there.
    Just can't seem to figure out what goes where...

    Any help appreciated.
  2. Even a pic of the back of a dash to see where the cables go would help....

    No picture but hope this will steer you right. 51 merc cable goes from the dash thru the firewall to the little handle on top of the fresh air steel tube. That is your fresh air on the left the other one goes from the dash to firewall along to the heater box. A third one goes to the fresh on right side from heater box
    Hope this isn’t to confusing and if it is i can try to get a picture tomorrow but not easy under the dash.
