Yamaha Trim/Tilt Guage

[TiredOfWorking]

I have a '03 Lund 1675 Explorer with a '03 Yamaha 90 4 stroke. Last year the trim/tilt guage started reading incorrectly. It reads higher than it should. It is consistant and I have adjusted to it, but is there any way to calibrate this? I have the outboard service manual, but this is not mentioned.

You're only option on this is to adjust it... there is no calibration procedure.

There must be some kind of sensor that tells the guage what position the trim/tilt is in. Can't that be adjusted?

[VMS]

there is...

If you tilt your motor all the way up, the little tilt lever should be on the port side of the motor (if memory serves me correctly). To adjust your trim gauge, you need to loosen the two screws on the sending lever, and adjust it up or down as needed. The screw holes are slotted on the sensor, allowing you to adjust. It will take a little while to get things right, but it is not hard to do...

Good luck with it..

VMS is correct in his adjustment procedure...

I appologize... last night when I responded to your post I read your post to say that you already adjusted the sender instead of what you wrote, which said you've adjusted to it...

Adjust the sender and you should be in good shape...

I have the same problem with the same motor. I just printed the fix and will give it a whirl tonight...

Turns out the trim sender cam was cracked. From what I have found on the Internet, this is a common problem. Of course, there was not a Yamaha parts dealer within 60 miles that had one in stock. I found them online for $1.77 each. Since I was going to pay $8.95 S&H, I bought 3 of them.

I have now broken my second trim cam. Where did you order those cams? That's a good price. I believe the first cam was sold to me by a dealer for about $15!...or do you want to sell me one?

[TiredOfWorking]

I ordered them from boats.net. Remember to order the screws also. I forgot to, and now I have 3 cams, but only one screw.

Can you post some pics on what and where the trim cam sender is? I am glad that you had the prob figured. I am actually quite surprised and upset that some authorized Yamaha dealers have no idea at all.

[Playin Hooky]

May be hard to get a pic that will be clear enough to help (I cannot on my boat) The cam clamps on the steering tube that runs under the motor cowling just above and inside your transom . It is just about centered on that tube. You probably cannot tell it is broken but it will slip when you push or twist it gently. From the front it looks like a simple black band with a SS phillips head screw holding it on. (Probably got a lot of grease on it.) Next to it is a pot switch that is in contact with the cam when the motor is down. There is a chance that the pot is actually stuck and the cam is ok, but probably not. (I had that on different Yamaha.) Removing the cam is easy, just unscrew the screw and it will come right off. Be careful replacing it; you can break the new one...but that will be obvious when you see the new cam...a real cheap bit of plastic, designed to break

From what I have heard, I will need all three cams eventually. If you do order them online, I would be grateful if you picked up a couple extra screws. I would be happy to buy them off of you.

Sorry, already ordered, but you're right, if you keep that motor you will be replacing that cam over and over. My motor is a 2000 model; replaced the first one in 2002; now replacing in 2006 (didn't use boat at all in 2005).

Unless you drop the screw overboard, you should be able to re-use the same screw. Mine has been consistently in salt water and it looks new. In essence it's nothing more than a #10 Stainless steel sheet metal screw with the tip ground flat.

Just replaced the cam on mine, and my replacement part was actually made of metal. Those engineers at Yamaha must read the forms...

Anyway, now that it is on, how do I go about properly adjusting the motor. The cam is hitting the little lever right when the motor contacts the tilt rods, but nothing happens on the gauge.

What else could it be?

[Chapo]

I have also replaced the trim sensor on my 01 Yamaha 90hp, replaced the old plastic one with metal and haven't had a problem in 2 years.

[Chode2235]

I am thinking it may be the actual sender unit. I can move the little spring loaded arm by hand and never see any change on the gauge.

Otherwise, although the gauge lights up, but how do I know the wiring is good. Can I check the volts somehow?

[Northlander]

Not to hyjack but how do I get my speedo working again? It went on me about a month ago. Not a big deal because I have gps and thats true speed but I just like everything working in my boat ya know.

And I thought I was hijacking this 4 yr old thread... Ha.
