Yamaha trim gauges not calibrated

[valmorel]

Hi
I have twin Yamaha 150 4 strokes installed on my 2007 26' Glacier Bay.

I just picked up the boat from my dealer. They had to replace the trim pump on the starboard engine.

One of the complaints I had when I brought the boat to the dealer was that the trim indicators on the tachs were out of sync. The gauges for both of the engines were not accurate. The indicators would move when the engines were raised or lowered, but, for example, the trim indicator would show about 50% when the engine was all of the way down.

Now that I just got the boat back, the starboard indicator is fairly accurate, but it still shows 2 bars when the engine is all the way down. The port engine shows 3 or 4 bars when the engine is all the way down.

Are these indicators easy to adjust?

I know I can bring the boat back to the dealer, and it will be repaired under warrany, but I keep the boat on a lift behind my house. Besides that, I don't have a vehicle large enough to tow the boat so I have to get a friend and borrow his truck to tow the boat. In other words, it's a real hassle.

Any help you can give will be greatly appreciated.

Val

Re: Yamaha trim gauges not calibrated

can you tell us if you have command link guages or standrd digital guages, the trim adjutment method is very different for both styles.
however both are easy.

Re: Yamaha trim gauges not calibrated

The gauges are digital and the trim bar graphs are part of the tachometers.

The engines also have the fuel management gauges that read speed, fuel consumption, MPG, etc.

Does that answer your question about what type I have?

Thanks for your help.

Re: Yamaha trim gauges not calibrated

I just checked the Yamaha website and it appears I have command link gauges. Sorry, I should have checked there before I posted my last reply.

Re: Yamaha trim gauges not calibrated

are they square or round?
do they display welcome when you turn on the key just before they self test and initilize the display ?

Re: Yamaha trim gauges not calibrated

Hi
The gauges are round and there is no message of any kind. When the key is turned on, the gauges read "0"'s.

Re: Yamaha trim gauges not calibrated

can you post a picture of them?
we MUST ID which style you have as the procedure is very different for digital VS command link.
both are easy,command link is incredibly simple, but both require different procedures.
sounds like you may need to use the dealer locator function and find a place with at least 1 master tech. 5 star just doesnt cut it .
any time your at a dealer they need to have at least fuel and electrical certs on the wall.

Hi
Here is a picture of the fuel management gauge. I tool a picture of the Tach, but it didn't come out. If this picture doesn't identify the type of gauge and a picture of the tach will help, let me know and I will take one.

Re: Yamaha trim gauges not calibrated

looks like the standard 6y5 gauge.
to adjust the trim senders look on the engines just inder the steering tiller.
you will see a plastic ring,called a cam, with a #3 phillips screw head.this ring clamps around the tilt tube and its arm operates the trim sender cam.

turn both keys on,trim both full down,loosen that screw and adust the rings until both engines barely show 1 bar, tighten the screw,tilt the engines until the trim rams are fuly extended, now both should show 6 bars. it can take a while but its doable.
the other way is to use a DVM and adjust both cams to the same ohms reading when the gauge shows 1 bar all the way down

Re: Yamaha trim gauges not calibrated

Thank you for the help Rodbolt!
You were right, it was pretty easy.
I noticed while I was adjusting the cam that the rubber sleeve that holds the wires and cables going to the motor was torn, right where it enters the motor housing. In heavy seas, water can get into the motor housing through that tear. I'm sure that is covered under warranty, and that seems pretty serious to me. Unfortunately, I am going to have to take the boat back to the dealer anyway.
Oh well, thank you for all of your help.

Re: Yamaha trim gauges not calibrated

first question I am going to ask is : ya really think a torn rubber grommet is a yamaha defect or was it caused by a technician?
if its a yamaha defect expect it to be warrenty,if not actually defective dont expect it.
if it isnt a manufacturing defect then you have to prove the dealership tech tore it and ask the dealership to pay to remove the wireing and replace the grommet.
myself,with the price of gas, I would simply inject it full of silicone and ignore it.
if your in seas heavy enough to bury that grommet you need to check the helmsman.
but in anycase good luck with it and sorry you had to adjust the cams yourself, first sign you need to find a real dealership though.
