power tilt on an evinrude 70 hp

[billmyers]

i just bought a 1986 70 hp evinrude motor. it has power tilt and i dont know how to hook it up. i have an OMC power tilt switch on the dash that has 3 prongs on the back. the tilt motor has 3 wires coming from it 1-red 1-blue 1- black. how do they hook up.

Re: power tilt on an evinrude 70 hp

You sure you have a three wire trim motor? A 1986 should have a two wire motor. Maybe the motor is older. <br /><br />Let us know. Good luck!

it has 3 wires red,black,blue<br /><br />it is model #e70elcd<br /><br />i dont know what to do?

Re: power tilt on an evinrude 70 hp

Then you must have a solenoid rather than two relays. Right?<br /><br />Let us know!

Re: power tilt on an evinrude 70 hp

i dont know. i had a 1982 50 hp evinrude that didnt run so i got this 70 evinrude. the person that got the motor from took the 50 off the boat, the cable on the 50 ran all the way to the dash so he just unpluged it (the OMC switch on the dash has 3 prongs on back of it) the 70 just had a short cable on it (4ft)but the plug was differant type smaller than the dash plug is there supposed to be some type of relay? where do i get one?

i tryed hooking the wires to a battery to see what was up and down but nothing happened at all i just dont know?

Should be red, green and blue. The red being hot to the center post and the green being the down wire, with blue been up. Green grass down, Blue sky up..<br /><br /> Somewhere someone spliced into the harness with different color wire than what OMC used. I would assume the red is still the hot out of the trim box. Just try touching the red to the blue or black and see what the trim does. It should also work by putting the black(neg) and the blue(pos) directly to the battery. You just reverse them to make the trim run the other way. This is what the relays do in the trim box, reverse the polarity.

what is a trim box these wires run from a little motor theres two metalic hydralic lines running from the bottom of the motor but theres no trim box

Never worked on one but.....<br />-black = ground (-)<br />-red = up (+)<br />-blue = down (+)<br />Is there a plug on the end of the wires?<br />This system uses a magnetic switch (alias solenoid). Manual doesn't say where its located, but I'll bet its under the hood possibly on the engine. It may look like a round black plastic hockey puck with wires coming off it. If you can find it, we'll continue.....<br />

Not positive, but i believe that trim system works off two standard 30a bosch style relays located in the trim box. Top of the motor behind the flywheel should be a black rectangle shaped box with 2 screws holding the cover on. Open it and there will be 2 relays inside, switch being green and blue for up and down, and black or red as input to your switch. Should have 4 other wires, + and - from the battery, and 2 that reverse polarity to the trim motor. you should be able to trace your wires from there.

Re: power tilt on an evinrude 70 hp

i coudnt find anything under the hood. this motor has a little motor beside it that is the same color as the motor. it has a cable coming from it that has 3 wires in it a red one a black one and a blue one (these are heavy gague wire) it was about 4 feet long with a female plug in. there are 2 steel lines running from the botton of the little motor to the outboard. there are no wires running to the motor itself. hooking a batery to the wires has no effect at all. it seams im missing something. this is my first boat. its a 24 foot pontoon?

Re: power tilt on an evinrude 70 hp

Its like Mike M2 said OEM is 2 wire motor with 2 relays. If the relays are not on the block, I would be looking for the seller.

Re: power tilt on an evinrude 70 hp

what exactally dose the thing look like i couldnt find any wires running from this unit to the motor?

Re: power tilt on an evinrude 70 hp

Are you saying the tilt motor is OUTSIDE of the stern brackets? In other words, with the motor all the way down you can still see the tilt motor?<br /><br />Let us know!

 

[Dhadley]

Re: power tilt on an evinrude 70 hp

If the tilt motor is outside and the tilt cylinder is INSIDE the stern brackets you are missing a harness part number 172539.<br /><br />Good luck!

Re: power tilt on an evinrude 70 hp

Bill, you may have more problems than just finding the relays (or one solenoid as per manual). You said you tried powering up these wires and nothing happened, right? Did you try black to negative and red or blue(one at a time) to positive? The only color code in the manual that matches that code (that I've found)uses a series-wound motor, what that means to you is.....do not put red and green across the battery. This may burn the field windings. Try black to - and red to + and the tilt should rise. Black to - and blue to + and it should lower. If it doesn't, you may have tilt-motor problems as well. If it does work as it should, rewiring a generic relay will cost about $10.00 ....not the end of the world.<br />

Re: power tilt on an evinrude 70 hp

I think what Billmyers is describing is the tilt, not trim and tilt. Of course he said that from the begining and I assumed (see? got me again!) he ment trim and tilt. If he has what I think he has all he needs is that harness. There wont be any relays and it is a 3 wire motor with 2 SS lines under it.<br /><br />Hey Billmyers! Let us know!

Re: power tilt on an evinrude 70 hp

the guy i got it from said it had tilt and trim? who knows? what you decribed is what i have so how do you hook it up? you guys are life savers!!!! thanks for your time. i raced stock cars all my life but boats are harder to figure out!

Re: power tilt on an evinrude 70 hp

billmyers -- If you can answer my last two posts I think we can figure it out. If you have what I think you have all you need is that harness and it just plugs in to your switch and your lead from the motor. You won't need solenoids or relays but it is tilt only.<br /><br />BTW -- I did stock cars too and I think boats are much easier! LOL! Both are a ton of fun!<br /><br />Recheck the posts and you will see the part number for the harness too.<br /><br />WE'll be waiting!
