I have spent the better part of a rainy day trying to educate myself a little about a new to me Yamaha F115. I bought the engine (used) a few months ago with no controls or wiring. I bought a used 703 control unit and also bought a multifunction digital tach (ebay, used) that based on something I found when I googled it made me think it was compatible with my other parts.
I believe the engine is a 2001. The serial number plate shows:
F115AET
68V X 702836
S
I have downloaded PDF's of manuals trying to find the most correct one, but the "AET" doesn't seem to be that common. For the life of me I can't figure out which service manual I want/need (lots of parts numbers, no years covered on the covers).
My biggest problem at this moment is determining if the tach I bought can be made to work with my motor. According to the Ebay ad, it is a "6Y5-8350T-D0-00". After having received it I realized that the included harness doesn't match up well with what I have. After more searching on the net I realized that images associate with that part number seemed to always show a tach with two buttons below the screen. The tach I have looks just like those, with no buttons on it. The harness that came with the tach has two plugs and four wires coming off of it...
the included engine harness has a 12 pin connector...
My motor has a ten pin connector with a single gray wire next to it, and this little three pin connector toward the front of the motor...
The 703 that I bought has the harness to the 10 pin on the engine.
I assume I bought the wrong tach, but since I know very, very little about the Yamahas in general, I am hoping that there is an adaptor that might save me.
I thank you for any help anyone is willing to provide.
