Ok, so I started looking into this data cable for my 2017 40hp Yamaha a couple of years ago. My Lowrance HDS9 graphs have the capability to display the info on my screens through the NMEA 2000 network that connects my two graphs and reads the gps and transducers
I really could not find any info specifically pertaining to my motor online. When I bought the cable two years ago, it says 50 hp and up! I finally spoke to a fellow at the boat show two years ago from Yamaha, that really seemed to know what he was talking about. He said it should still work and agreed that if I had the plug under the cowl, it “should” read the data available.
Well, finally, after being my overly cautious self (understatement of the year! Lol), I installed it! I am delighted that it gives me RPM’s, hours on engine, rate of fuel being consumed, and probably lots more! Hours was my main objective! I installed a little stand alone battery operated gauge a while back when it was new, but the thing eats batteries!
My fishing partner claims it will just be another distraction to keep me from fishing! Lol
