Johnson 150 tilt/ trim

[Gman 82 aquasport]

I have a 1992 Johnson 150 that I have mounted on the boat , but I do not have a wiring harness for it.I have the controls but not the plug in harness. I need to get the boat to a shop to have a harness found and other work done, but I must be able to tilt the motor up to tow it to them...Any body know an easy way to "hot wire" the tilt/trim for a minute to tilt the motor up that won't hurt or fry anything? I thought about just hooking the battery cables up to the motor as usual and putting a jumper wire to the tilt button on the side of the motor and find the one that moves it up.. would this hurt it or should the jumper be fused as to not overload the wire..or am I just way over thinking this....

go ahead and connect the battery it wont hurt i used a jump starter pack do it for a few seconds if you want it the other way just remove and swap wires around good luck iv had all sorts of dramas with mine lol

There's also a bypass valve you can open with a screw driver so that you can lift it manually

Re: Johnson 150 tilt/ trim

From what I have read on here the bypass valve is on the starboard side correct.... you are supposed to turn it a couple of turns to release. If you do this and tilt the motor will it hold it up if you re-tighten the screw or does it need to be braced up....Not near the motor right now but will be tomorrow....Thanks

Got home Monday morning and mounted the motor on my hull.... release/bypass valve on my 92 150 was on the port side, 3 1/2 turns to release ,pick up foot and set the brace and retighten screw, took 3 minutes....thanks for the help...

i have a 150 johnson ocean runner the trim was leaking as well as tilt , i got a new seal kit removed the unit from the boat took it in shop and rebuilt it, after the rebuild i put fluid in it and have bled it , i thought is was working but when you try to trim it down it does not go down, i thought i needed the wait of engine so i installed it to the boat and tried it now it wont go up or down and i cant get it bleed anybody have any ideal on this matter
