Thank you for this. My issue was the yellow trim tilt/starter 20 amp fuse. Traced 12 volts to solenoid which was a bit of a red herring since it showed 12 volts at positive connector. But, using the spare 20amp fuse everything worked. Of course the outstanding issues is why did the fuse blow in the first instance. Thanks though.

Agree, that something likely smoked the fuse in the first place, and on Yamaha, fuses just up and blowing themselves out for no reason is exceptionally rare

Can't tell you how thankful I am for your videos. I was completely convinced that my trim motor was out because the voltage looked fine at the relay, went through the whole trim motor replacement process (snap bolts, re-tapped holes and all), got everything reinstalled and still nothing - never a good feeling. Saw this video, jumped my motor wires straight the battery contacts and boom, motor worked fine. New relay is on the way!

I have searched all over the internet, including you tube. You have the BEST and most informative video on this subject that I can find. I want to thank you for taking the time to make this video. You just saved me hundreds of dollars. Well, I was going to start with changing the relay anyway, but you at least made me feel much better about ordering the part. Now I know without a doubt, the trim motor is good. Thanks again!!

Thank you for this, my EXACT problem. It was confusing me that I had proper voltages but still no joy in the down direction. Swapped the motor leads as you suggested and the problem swapped too.

Absolute banger of a video! Appreciate it man.

Thank you for this video. I have a 1999 Yamaha C60 TLRX and have trim/tilt relay issues as well. The motor would go down but not up. I bought an aftermarket relay but was still having the same issue but only in reverse. Took the motor out and had it bench tested and is ok. Long story short it turns out I replaced a bad relay with a junk relay... I did the voltage check between the blue and green terminals and only get voltage one way. I also did a continuity check between the black, blue and green terminals and showed no continuity between the black and the green terminal so the motor was loosing ground when trying to go up. Thanks again as this saved be a "boatload" of money (pun intended) because I was going to take the boat into the shop next week. I will just replace the relay again but with an OEM relay!

Yamaha had an issue with the shock mount pin and the tilt rod seizing into the transom/swivel bracket. Once the pin loses the ability to rotate, the tilt rod is usually on borrowed time. I've seen several of the F90's and F100's over the years which developed this problem and the tilt rod would snap near the ring at the end of the rod. Usually requires cutting the ends of the pin out of the bracket and then impacting out the remaining metal in the bracket. Not a fun job.

I'm having issues with the trim on the F70. It will click and go up as it should but does not go down, just clicks from the relay. No strange noise or other symptoms but sometimes it will go down like nothing is wrong. I'll start with checking the trim motor then move to the relay if no other suggestions. Thanks for the video.

Mine will not go up or down. I tried putting 12 volts directly into the green and blue and it arcs like a dead short. What could that be? Great vid thnx.

Fantastic thank you

I have a Yamaha 2001 F100 which apparently has been discontinued and is difficult to find parts. My power trim is allowing the lower unit to sag. Any thoughts on repair and any help finding seal kit for this motor. Maybe the same as F115.

Choppy irregular movement and sound usually indicates some internal issues such as air in the unit/ fluid leak, or trim motor starting to act up. Check fluid levels first and add fluid if needed, low fluid will wreak havoc. If you disconnected the trim motor leads from the relay and straight wired to known good 12V and ground, trim up is good and trim down is a solid consistent fail, likely there is an issue with the brushes/armature in the trim motor or issues in the trim motor wiring. If the trim motor leads get hot to the touch during testing, can also indicate corrosion related issues in the wiring itself. Most trim motors can be taken apart and brushes, armature etc cleaned or replaced, but there are also a couple of aftermarket sellers who make a good replacement motor that makes replacing the entire motor assembly a much less expensive and time consuming option. So, if everything else is good from trim switches all the way to the relay, odds are high that the trim motor is struggling.

Yes, If fluid level is low, there is likely air in the housing/cylinders. Air will cause an irregular sound and random changes in pitch from the trim motor and air pushed through the unit will make a faint popping sound. If no air in the unit, and the only sounds you're hearing are odd changes in pitch from the trim motor, there is also a chance the trim motor is in early stage of failure. Most trim motors are on borrowed time after about 10 years in service

I have the same problem, no trim up. I check the current on blue and green and it was okay. I took a wire from hot cable direkt to the blue and get like a short circuit! No moving. What can be the problem

Tough to say exactly without having the unit in front of me. BIt sounds like you've already done this process, but I have to run through: Disconnect the trim motor leads from the relay, put a volt meter on the green and blue studs on the relay, check trim switches at handle and on the pan, up and down. You should get 12V on all checks up and down, both switches. If the relay is in early stages of failure, it may give you good voltage on all checks but when you put a load on it, such as a trim motor, the relay won't be able to deliver any amp load at 12V. This does not sound like your situation. Next isolate the trim motor leads. Connect green to a known good ground, put the blue to 12V (It is better If you have a battery pack or jump box so that you can do this test without using the engine cabling this is better since you are not risking any fuses or a stray short damaging anything on the motor electronics). With green to ground and putting voltage to blue, if you are getting any sort of arc or the wire is getting hot and no motion or sound on the trim motor, the trim motor is damaged and likely has an internal short and needs to be replaced.

Not difficult, Diy? For Both. I'm pretty Handy and savvy. Thanks

Trim motor replacement is easy and fast if the entire assembly can be removed from the brackets/ motor and full access to the mounting screws. The re-seal is also pretty easy job, couple of things to look out for, but not too bad for the mechanically inclined.

If the trim switch on the engine side works and nothing on the remote control handle, more often than not it is a problem with the switch in the remote control handle or the connections where the switch ties into the Yamaha main harness inside the console. Look in the console for a 3 wire connection with red, blue, green wires connected with bullet connectors with one lead going up toward the control box and the other lead going into the main harness. It is not unusual for these connections to be disturbed or accidentally disconnected if a tech is doing electrical repair or install in the vicinity. Normally I would disconnect there and check the harness side for 12V power by connecting the red to the blue and then the red to the green. Connecting these will actuate the trim motor up and down. Blue to the sky, green to the earth. If the harness side checks out good and then you still have an issue after reconnecting the remote control, it is likely that the switch in the control handle has failed, which is very common. You can Ohm out the handle switch side (disconnected) as well by checking continuity between red to green and red to blue while holding the switch up or down (which will close the circuit) and should give continuity. If no continuity during this test, the switch is definitely toast. As for any other electrical issues in the boat systems or other console electrical fails, again it is not unusual for connectors to get disconnected or loosened while electrical work is happening in the area. Would check all connections and breakers for good hot and ground and work down the chain from there. This can be time consuming. Often if serveral systems are down at the same time, it is best to trace them to their common source and check connectivity there (I.E. the 10 AWG mains that run from the battery control switch to the console to provide power to the switch panel). A fail on the mains will shut alot of stuff down.

If you are getting a click sound on the up and down, and no sound from the trim motor, the failure could be either one, usually not both. Easiest way to isolate the failure is to disconnect the trim motor leads from the relay, and connect them to a known good 12V hot and ground. If the relay spins normally in both directions with the leads connected, then reversed, the trim motor is usually good and the relay is bad. If you do this test and the trim motor doesnt make a sound, it is usually inoperable and needs to be replaced, and the relay is fine. Do not attempt this test with trim motors with more than 2 leads. Wear gloves and eye protection since there may be sparks and wire terminals may heat up on contact with a live voltage source. Best way is cut the power to the motor via the battery switch, securely connect the trim leads to hot and ground with alligator clips or similar and then power the motor back up with the battery switch. This will usually prevent any sparks or heated wire leads produced by arcing as the lead/terminals approach a hot source and is generally safer.

Thanks for the vid. Trying to fix mine for a while now. Got a part in that was pointed out in other videos. I have a F90, it is the cube shaped relay with two wires located just above the relay you point out. Do you know what that is?

If it has two threaded 6mm holes in the face and two wires: one with a ring terminal and one wire with a bullet connector, it is likely to be the start relay. Usually costs around $100 to $110 if you bought a Yamaha OEM part. You should probably keep it, start relays have a pretty high failure rate after about 10 years or so in service

I'm struggling to grasp the "negative voltage" comment. This is a 12V DC system right? All you have powering the system is the battery. I saw the negative symbol displayed on the multi-meter, what's that all about on a DC system? Sorry if it's an elementary question.

@outboardst.comoutboardspec8631

The meter will display a negative symbol anytime it picks up reversed polarity. So, if you place the hot lead on a battery negative terminal and the ground lead on battery hot terminal, it will normally give you a negative voltage value. How this info pertains the power tilt trim and Yamaha trim relays: Yamaha 2 wire trim motors spin a drive rod in both directions, forward and reverse or clockwise and counter. To trim up, the rod spins one way and to trim down the motor spins the rod the opposite way. The direction of rotation is controlled by the polarity of the feed coming through the trim motor wiring. To trim up, the blue lead gets positive 12V and the green lead gets battery ground. To trim down, the green lead gets positive 12V and the blue lead gets battery ground. The trim motor leads are bolted into place on the relay for obvious reasons. It would be impossible to safely operate this system on a running motor by manually moving the trim motor leads from hot to ground and vice versa every time one needed to adjust trim position. The trim relay takes care of that task by reversing polarity of the voltage supply to the attached trim motor leads as needed. In the video, you could see that the battery voltage was positive when the up switch was actuated and negative when the down switch was actuated. I do that check to verify that correct voltage is actually reaching the trim wire terminals on the relay for up and down. This relay was allowing voltage through as designed but could not handle the required amp draw needed to actually power the tilt trim motor, which is a very common failure on Yamaha trim relays.

Apack, your puzzlement is understandable. I just figured this out today as I was replacing this relay. Here's how it works. Both green and blue terminals are hot. When you throw the switch for tilt up the relay grounds the green terminal. When you throw the switch for down the relay grounds the blue terminal. So, if you place your voltmeter across the blue and green terminals you'll get + 12.xxx volts when you throw the switch one way and - 12.xxx volts when you throw it the other way. The tilt motor only has two leads. The motor spins one way for one polarity and the other way for the reverse polarity. The Blue and Green wires take turns playing Ground.

Disconnect and Isolate the trim motor, if it fails testing when you straight wire the trim motor leads to known, good hot and ground, there is a failure confined to the trim motor/trim motor leads. If the trim motor checks out good, 100% operational, then check the relay, and by default the rest of the system all the way to the switches, by putting meter leads on both relay studs and push the switch both directions, while checking for 12V DC and neg 12V DC. This will tell you the relay is allowing voltage through and reversing polarity to spec, but doesn't tell you if the relay can handle the required amp load at that voltage. If the trim motor is tested/proven to be operating normally, re-connect to the trim motor to the relay and test again at the switch. Sometimes the relay will give normal voltage with a meter, but fail when connected to a load. If you get nothing when the good trim motor is reconnected, odds are good that the relay is failing and needs replacement. Relays are expensive, so its usually worth a bit of extra time to verify failure/ or intermittent failure. Intermittent fail will become 100% fail at some point.

So, yes, definitely make sure it has plenty of fluid. Whether the issue is caused by air bubbles or trim motor malfunction, the ptt reservoir will need to be topped off to find/eliminate the cause. Sometimes, you can top off the fluid, let the motor down by letting out the manual release screw, bring it back up and loosen the reservoir cap to vent out air/add fluid as needed.
