Adjusting Tilt/Trim Gauge Reading

9 posts in this topic

Anyone have experience adjusting a tilt/trim gauge so it reads correctly again? When my motor is all the way down the gauge reads only half-down... Just kind of an annoyance more than anything.

'05 Crestliner Fishhawk 1750 w/ Yamaha F90

Thanks in advance for any helpful replies.

nthomps66,

Is it moving when you start to trim up? If not it could be the sending unit. I had to replace the gauge on my boat, relatively inexpensive and pretty straight forward.I don't know that there is any adjustments to the gauge itself. You are right it is an annoyance, you wonder if you're trimmed properly or not, usually the tach will tell you.

The mounting tabs on yous sender are very likely slots, allowing you to rotate the housing to adjust your reading.

Your sender is found here (circled)

Hi marine_man, (or anyone)

I have a similar question; I recently purchased a trim gage for my 07 Sylvan. I also have a F115 Yamaha 4 stroke. The wiring harness has a 4 wire clip that plugs right into the back of the gage right where the gage mounts I figured this to be a piece of cake to install. BUT it has just been one big pain in the back side. When I plug in the gage the illumination light works when I turn on the lights but it has no needle moving at all.

Question 1,

Does the engine need to be running to have these gages work? If so that may be my problem, but was really hoping it worked when the master switch was on regardless of engine running or not.

Question 2,

How do these senders work? I only can trace 2 wires out of the sender, one redish/pink and one black. I figured there would be a “Hot” “Ground” & “Signal”?? Is it grounded how through the mounting?

Question 3,

These wires go out the left side and wrap back into the engine. They end up going to the middle back side of the fuse box. Then they are taped up in a harness that is tough to see.

I don’t really feel comfortable digging in to it any further. Do you know what color wires are fed up to the dash?

Thanks for any help provided.

Needless to say I am very disappointed with the dealer I bought this brand new boat at just two years ago. I even bought the trim gage from them and they claim they cannot get an answer from Sylvan or Yamaha.

Thanks Again!!

Thanks Marine Man, I have the same issue on my F115 and always wondered how to adjust it.

No the engine does not not need to be running but the key switch needs to be in the run position and obviously the motor must be moving up or down to see needle movement.

The sender is actually a rheostat or potentiometer. As the motor move up or down, the sender is internaly rotated, changing resistance thus changing the needle position on the guage.

I would tend to believe the colors would remain the same at the dash. I would think they would be part of the connector you mentioned.

    • You have no idea....               Suck it up, buttercup...  
    • That was obviously his Republican side...
    • lambjm - keep at it. If you do, you stand a great chance of fishing for possibly decades to come.    Inspirational to me, and hopefully others, is our 85 year old neighbor in Hovland who finished up logging our land this past spring. He logs in a one man operation every day, except Sundays, and a nice day every now and again to fish with his wife.    He has been logging continually for 66 years.   Like clockwork he gets to the landing everyday by 8:30, takes a 15 min break at 10:30, a half hour lunch break at 12, and a 15 min break at 3 before quitting at 4:30. A few days last winter I was out on the land making firewood and clearing trails, and could barely keep up with his schedule. He plans to keep at it as long as he is able.    My wife and I saw him last winter, as we rounded the corner of our road, standing atop a 10' pile of aspen logs with a cant hook or axe in one hand, waving with the other. He appeared as a man less than half his age in terms of agility and stature.   Genetics are a key, but staying interested and active in an outdoor activity is very important to a long and healthy life.     
    • That is because he was fooled into believing in trickle down economics and the idea that cutting taxes in and of itself would solve the budget problem.   Some are still fooled today.
    • Starve the beast, only the beast got stuff on credit.   Reagan didn't seem to be concerned too much about debt.
    • We already know Uncle Bill's response though:  
    • That is a very nice Pimple spear!   They are hard to find. I bought a couple of them from Jerry Kelm. He said Pimple used spring steel from hay rake tines to make the spear tines.    I have not seen one in person with chromed or nickel finish like that, but there is a picture of one that looks exactly like yours on page 215 of  the book "Ice Fishing Spears" by Marcel Salive. I actually wonder if it is the same spear. I heard Mr. Salive was selling off some spears about 5 years ago.    Are you going to be our tomorrow? If so PM me and I will bring the book out to give you a look. TS and I are going to out in the morning.
