What wire is for

[fish46]

I have a 1974 Starcraft aluminam boat and there's a small block on the transom under the motor. Inside the boat there is a bear wire coming from the block does it go conected to the battary or where does it go

Pics would help and perhaps let us know what motor this is. I have a box on my transom and the relay's and what not for my motor's power tilt and trim system.

the box is not connected to motor or anything els.It looks like a ground wire

fish46, you really need to get a picture up so we can see what you are trying to describe. You will get the best info with a picture, with you're attempt at a description the only thing anyone can do is speculate what it could be. And with that being said it could be a good number of things.

fish46 try reading this link. Make you're photos 640X480 and use the IMG option to insert the pics.

Re: What wire is for

the box i'm talking about is under the board and the wire inside the boat is the one i done know where to connect. does it go to the negetive on battery

Re: What wire is for

I see what I believe to be the Motor I D plate on the photo, on the tilt bracket. The numbers on it should allow you to get the info you need fron the Iboat Motor forum. The motor is a tilt and not a trim and tilt the Trim and tilt have two pistons and the tilt only has the one in the photo. The Iboat forum has a lot of diagrams and the Motor mfg. as well. should be able to find what you need and figure out what you have.The single wire is definatly a ground which should run to the helm contrell area.

Re: What wire is for

I'm not positive, but I'll take a shot at it and say it's a bonding wire to an external anode, which doesn't apear to be on the outside any longer.

In more modern boats, this wire would be 10 ga, and green. It's isolated from the hull by insolators and connects to an external anode, then bonds all the internal metal components in the boat, to cut down on electrolosis. Could be, in an aluminum boat, it's not isolated from the hull.

Do not connect such bonding wires to a battery. No wires from a battery should be connected to an aluminum hull.

Re: What wire is for

fish46 from the first photo it looks to be on the starboard side, the second photo shows to port side. Dose what the wire bolts to go thru the transom?

The only thing I can think of, other than what Bob said. Is as you said a ground, however I see no purpose for it and as said you wouldn't want to use it for that purpose. If it is not currently connected to anything and everything works for you on the boat I would just forget about it.

I think it's conneted to a external anode. If so sould that wire be conected to anything it cuz it has a ring st the end of the wire

Re: What wire is for

Connect it to a ground stud on the engine block. Any bolt, or stud, it can reach will do, that goes to the head or block. Don't combine it with the battery ground.

That's how we did it with the yachts we built for Rampage. All our bonding wires were run to a bonding block, same as a ground block used for helm instruments, but designated only for bonding to the anode.

All metal componants were bonded together with several different 10 ga wires. Generator, fuel filters, water strainers, engines, fuel tanks, steering system,to this block, and ran from forward compartment, engine compartment, and rear compartment, each had this bonding block tied together, then anode. You could do an ohm test and get a reading on any metal in that boat, to the anode = Bonded, aka continuity.
