Below are some additional forum policies in hopes of all iboats members will follow, Thank you.

1. Please do not reply to old topics or hijack existing topics. Old topics of a technical nature are like a library book, Please do not write in them.

2. Old topics should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone elseís topic (aka hijack) with your own question, even if it is similar. If you have a question that has not been covered to your satisfaction in the archives, it is always best to start a new topic of your own.

4. If you have a question for the original poster (OP) and the topic is over 30 days old, send the OP a PM, he may not even visit the forums any longer, or may not notice your question in the old topic.

5. By starting your own topic, you will receive the maximum number of views by forum helpers that may not even notice your question when itís posted at the end of someone elseís topic. And those answers will be specific to your particular issue.

6. Please do not post to topics that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any topic that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old topic.

7. Posting at the end of any topic is considered to be hijacking the original posters topic which in turn subjects the topic to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive topic asking you not to reply to old topics. The Red banner will read: Please note this topic has been inactive for 90 days. For the best results, please start a new topic.

Thank you all in advance for doing your part in helping iboats run a smooth ship.

  • wiring diagram please, tilt trim

    does anyone have a simple wiring diagram that will show me what i need to hook up my 2 wire tilt trim i purchased on ebay.the boat and motor never came with power tt so i will be starting from scratch.i currently just use small jumperclips to make the tilt go up.then i reverse the positive and negative to go down.i thought all i needed was a switch and a couple relays to make this system work.when i went down to order the relays and switch, the parts lady wanted to sell me the whole tilt trim gauge package which would come with a boat had the tilt trim unit been stock equipment.this is for a 90 hp 1981 evinrude but i believe the tt unit is 10 years newer than the engine.is it possible to hook this unit up to a simple switch by the steering wheel or do i have to order the whole tt gauge package?

    Sorry no. A switch can be installed in the dash but all it will control is the relay pack, i'm at work now get off at 7, when i get home i'll look at mine and tell you. For starters you will need (2) SPDT relays (Single Pole Double Throw relays) and a pre-wired dual relay socket. You can find these at a car alarm shop, radio shack, might be able to do a search where you live. You have to wires coming from you motor correct green and blue??

          Relay 101

          __87

          l __87a l
          86 85

          l
          30


          You will need (2) Bosch 12volt 20/30 amp relays
          (2) relay socket holders or a few spade connects and 12 to 14 guage wire for the power cables and 16-18 for the switch wiring.

          Wiring

          Battery 12-14 guage
          Red + to 87 on each relay
          Black - to 87a on each relay then jumper 87a to 85 on each relay.
          (jumper 87a to 85 on each relay by itself don't jumper then together)

          Motor
          Green to 30 on relay
          Blue to 30 on the other relay

          Switch On-Off-On 16-18 guage
          top to 86 on one relay
          middle to the red +
          bottom to 86 on the other relay


          Put a fuse near the battery on the red +.
          Recheck your wiring then figure out up and down.

              Or, you can get a 3 position high amp momentary switch. Positive and negative to the bottom legs. Jumper wires to the opposite side from each bottom leg to the top legs. You will have a X wiring arrangement. Then your 2 wires from your T&T to the middle 2 legs.

                        Re: wiring diagram please, tilt trim

                        Hi, I tried hooking up my 5 post relays according to your instructions, but I think I did something wrong. The battery sparked when I tried to reattach the neg. terminal. I found a diagram here in the forums, but it seems like it uses two 4 post relays. http://home.swfla.rr.com/netsvc/trim%20wiring.pdf It didn't work so I bought 5 post relays. Each post is labeled 30, 85, 86, 87 and 87. I have a two wire tilt, green and blue. Works fine in both directions when attaching to a battery.

                        Any help is appreciated.
