1. Do you have a wiring diagram for an 1986 Mariner 40HP?

   Thanks

   • Hi Jim, thanks for the comment.

     I think the owner handbook for the Mariner 40HP has one but you can also check the Mariner Model Guide to see if the service manual is shared across models as they often were.

     Check here: https://outboardmanuals.net/outboard-manufacturers/mariner-outboard-motor-model-identification/

     Let me know if you can’t find what you’re after and I’ll do some digging through the archive.

     Thanks
     John.

2. Hi John, thanks for loading these up.

   Did you start this because BBB Industries no longer provide wiring diagrams? I used their resources section of the site for years but now can’t seem to access it anymore.

   Do you know what happened to them?

3. Hi Scooter, yeah I heard it either got pulled down or went behind some kind of restricted access section.

   There is a bit of thread on Reddit here: https://www.reddit.com/r/cars/comments/f6bcx9/bbb_industries_is_no_longer_offering_wiring/

   Not sure if it will come back again but I know lots of people used it.

   Let me know what you need.

   Thanks!

5. Hi, I’m looking for a wiring diagram for a smokercraft pro tiller 50Hp. I’m trying to troubleshoot boat side electronics issues not the motor. Not original boat owner and something fishy is going on. Fuel gage reads full with power on, always. Nav switch has Both red and green switch lites illuminated, and blows the 20A main fuse.

   • Hi John, thanks for the comment. Not sure I can help with any manual content but if you have multiple electrical quirks as the same time that usually means a fundamental issue such as a short in the circuit. You might have to take components out one at a time to troubleshoot to isolate the root cause.

     Sorry can’t be more helpful.

6. I am looking for a wiring diagram for a 2003 Yamaha 115 two stroke outboard motor. Could you please let me know if you have this wiring diagram.

   • Hi Tommy, thanks for the commment.

     I’ve had a look through the manuals not yet on the site and unfortunately I don’t have one to cover the Yamaha 115hp. Will keep and eye out for it on my travels though.

     John.
