I have a 1987 Skeeter Bass Boat with Johnson controls, the tilt/trim plug is a male 5 pin, with 1Greeen w/ white stripe, 1Red w/white stripe, 1Blue w/white stripe, 1White w/brown stripe, 1Black w/ brown stripe wires. The T/T I'm putting on is a 1974 115hp Johnson with 4 wires, 3 wires that look like 8 gauge red, blue and black and 1 black wire that looks like 10 gauge. I need help putting this together, I found this topic but the answer is missing http://forums.iboats.com/showthread....tilt+trim+plug

Thanks

I think you're trying to mix apples and oranges.  If I remember right, the 87 motor has the relay control box on the side of the motor and the 74 model has the relay control box mounted in the boat.  I think you're going to find on the 87 motor, those are all control wires and the trim motor wires are in a seperate connector.   On the 74 motor, you are seeing trim motor wires and control wires.

There are also two different trim motors, there is a two wire and a three wire motor.  You will have to look at the motors and make sure one is not a two wire and one is a three wire 

Any time your dealing with OMC motors, The green wires are going to be the down function and the blue wires are going to be the up function.  Green for grass, blue for sky. 

On the 87, the red/white is power to the trim switch and the switch.  The green/white is the down side of the trim switch.  The blue/white is the up side of the trim switch.  The black/brown and white brown should go to the trim guage with the black/brown being the signal and the white/brown being the ground.  If the guage works backwards, these are reversed.

In the 74 motor, the larger guage wires are going to the motor, they are usually blue and green but have seen black and white.  On the two wire, it's not critical if you hook them backwards, the motor will just run the opposite direction so when you trim up, it goes down.  If that happens, just switch the two wires.   On a three wire motor, you have to get the common, probably the red wire, right or it may only work in one direction or not at all.

I think you're going to run into all kinds of problems getting these two interchanged.

Thanks Way2slow, great info, I have one of our electricians from work stopping over to look at it.

Thanks Again

I got it working but not correctly, if I run wires from the battery it works fine, up and down real quick, now if I use the wires in the boat for tilt/trim it works but very very slow.

Too much internal resistance. The wire guage is too small, bad connections and/or the relay contact tips too small. The resistance is causing too much voltage drop and slowing the motor. This will also the wiring or contacts to overheat and possibly catch on fire if run too much.

Start with the common hot wire feeding the relays that run the motor and the negative. Measure the voltage across them and see how much voltage drop you have when you run the motor. Start where they connect at the battery and work your way all the way to the trim motor. Replace any wires that are dropping more than a few tenths voltage with larger wire. Chase the voltage drop and fix the problems

Way2slow, yu da man, I will check this out.

Thanks

I made the assumption you are using relays to control the T&T motor. If not, that's your main problem right off the bat. The T&T motor must have approx #10 wire for all positive and negative connections all the way from the battery, or the starter relay on top of the motor, to the T&T motor. The small control wires going to the switches in the handle and front of the boat are stickly control wires to Energize the relays. The up/down relays control the Large guage wires to the T&T motor needed to carry enough current to run the motor. The relays are wired so they apply battery voltage/current to the T&T in one direction and reverse the voltage/current in the other. The relays and large guage wires do all the work, the switches only tell the relays what to do.

Way2Slow is like the old E.F. Hutton commercials

When he posts everyone should listen.  I hang on every word he types.  Cant tell you how much I have learned from his posts regarding motors and wiring.  Thanks for all you post, brother.   

He's been good to me in the past and present

I make a motion to remove the tag line under his name that reads "been posting a long time" and replace it with "motor and wiring GURU"

Got it, I used the T/T switch from the back of the boat, the switch was already hot, ran red from T/T to up green to down hot in the middle and a separate ground, from there I hooked everything to throttle switch. Working great

Thanks
