2005 40 hsp tilt&trim wiring

[DaSuNele]

This is my first post . I have the above motor and have narrowed down the problem with my tilt and trim to the wire harness from what I will call the selenoid to the tilt motor . The problem is no yamaha dealer has the number of this wire harness . It has what appears to be a relay in the harness which is throwing the parts place off.I am thinking it is the relay , or whatever that part is ,that is my problem. Anyone know of the # for this harness ? Thanks

We don't have any listing for a 40HSP model number, recheck model number.

That is not the model number , it is the "horse power" of the 2005 4 stroke motor . If you indeed need the model number I can get that.

The trim relay is listed under Electrical Tab in parts catalog for your model outboard, Yamaha Outboard Parts

Thanks you so much for the info . If I may ask you another question regarding this mater . I have had the selenoid tested and also the tilt motor has been tested . They seem to work fine . The wire harness from the tilt selenoid to the tilt motor may be what is giving me the problem . There is a "relay" hard wired into this harness . Can this relay be bypassed , so it is hard wired ? What purpose is this "relay " ( if that indeed is what it is) ?Thanks again

#6 is the T&T relay

What part # are you calling the selenoid?

And what part # are you calling the "relay" hard wired into harness?

I believe , for the sake of our conversation , and because I call part #6 a selenoid and I think Yamaha may refer to part #6 as a relay , I am confusiong you with my terminology . Assuming part #6 is a "relay" I will change my description of the wire harness that has a small black sealed in line box that is on a wire harness coming off the relay.We thought that this small black sealed box was a relay of some type , thus the confusion on our end. Today while searching where all the wires run , off part#6 ( the relay) we found some wires that joined a bigger wire harness that runs towards the front and outter area of this tiller mount motor . We found 3 or4 wires that were just hanginging there with coils of other wires that the installer had in a corner of the boat . It appears that two of these wires , that had open end male connectors some how ,maybe bounced and were now making contact with each other . We are assuming that these two wires green and blue , being the same color of the wires that are on part #6 ( relay) are the up and down control wires for maybe a wire harness that would come from the front of a boat if the motor had been mounted with a console drive boat . After seperating these two wires , the t&t now works . What do you think . and thanks for your assistance .

If that fixed it then you should be good to go.

Sill confused on the black box though

If I can find the little black box and take a picture I will try and post it here . I can't make that promise , but maybe at a latter time . I actually am the owner of the boat and my friend is the more mechanically inclined on outboards of the two of us , so he knows which wire it is again . Thanks once again for your support and help.
