I think it can be done.Ezeke or HighTrim will probably have advice..Hang in there.

Re: two wire trim swap w/three wire

It can be done, but can we ask why you would like to go to the 3 wire setup?

It is usually the other way around

Re: two wire trim swap w/three wire

We used to do it all the time on the race boats. We found a 3 wire that was much faster. All you have to do is cut the "communication" wire between the two relays.

Re: two wire trim swap w/three wire

the trim motor on the 89' rusted through got water in the system someone gave me an old 75 hrs how do I go about wireing the older one to the newer controls?

 

[HighTrim]

Re: two wire trim swap w/three wire

Here is a visual to what Dhadley was saying. The first diagram is your current wiring, the second is how to modify it for a 2 wire motor. Let me know if you have any other questions. Good luck.

Re: two wire trim swap w/three wire

are the relays in the controls because I do have the older controls and can install them if I have to. I see the diagram but don't fully understand it when I tried to do it all I did was conect green with green and blue with blue it went up but not down.

Re: two wire trim swap w/three wire

I would like to use my current controls if you can explain in a language I can understand I'm a carpenter I understand wood not wires. I really apreciate yall's help so far thanks Jon.

Re: two wire trim swap w/three wire

Your remote control is irrelevant, and can be used. Here is a better picture of your current set up, before the modification you want to do.

Simply cut and disconnect the 2 ground wires, and ground the black wire from the trim motor to ground, as per the first set of diagrams provided. Now when there is no power to the relay, there is no connection, and when there is power, you are getting 12V, which will either raise or lower your motor, depending on the button being activated. In my second original diagram, imagine that the 3 wires coming up from the bottom of the page are coming from the trim motor.

What year are we talking about?

Re: two wire trim swap w/three wire

I hooked up the old relay box to the trim it works. Well there is a delay between going up and down if I try to go up or down suddenly is that normal? The motor still runs while I have the switch depressed it takes a few seconds till it goes up or down but If I'm running I would need instant transfer. Maybe the oil is low? If so where do I add new oil to the unit. Thanks Jon 89' motor putting on around 80'or so trim.

Re: two wire trim swap w/three wire

Im glad it worked for you.

There will be a large slotted screw in the front of the oil resevoir. First cycle the tilt fully out, top up the oil, cycle 5 to 6 times, bleeding the air from the system to the fully trimmed out position, re fill, cycle 5 to 6 times. Continue until full.

Re: two wire trim swap w/three wire

Is the delay caused by a lack of oil? Because the motor is off of the boat rite now and if it is I will put it back on so I can get it ready and fill the oil back up.

 

[HighTrim]

Re: two wire trim swap w/three wire

It is possible.

Also possible that there is a clogged passageway or internal valve, air in the system, etc...

Start with topping up the oil and bleeding the air.

Let us know what you find.

Re: two wire trim swap w/three wire

Also, does the delay happen when going from trim in to trim out, or when going from trim out to trim in, or both?

 

[topdogeye]

Re: two wire trim swap w/three wire

one other thing I have a good tac that I pulled off of the boat the 75 hrs came off of is the setting on the back of it the same for the 60 hrs or do I have to change it.

 

[HighTrim]

Re: two wire trim swap w/three wire

The rotary switch will remain the same.

Re: two wire trim swap w/three wire

thank you very much High Trim finding this forum is the best thing I have stumbled apon in quite some time for I do all my mechanic work and the books are limited. Thanks again Jon

Re: two wire trim swap w/three wire

Not a problem at all, but again, does the delay happen when going from trim in to trim out, or when going from trim out to trim in, or both?
