My 50hp tldi (2012 model with about 80 hrs) is making a chirping noise at idle. Does this sound normal?

Try it again. I don't know why the first one worked but the second one didn't . I set it so anyone can see it.

Yes it also makes the chirping noise when it's in the water. It either goes away or gets drowned out when I increase throttle on the water. Sounds like the air compressor?

Since you are in warranty, see what your dealer has to say.

I sent the video to my dealer. He is about a two hour drive away. He said it's a normal sounding air compressor, but I could bring it in for them to look at if I want, and that they would charge me to look at it. I also have a 90tldi I bought from them in 2014, and it does not make the chirping sound.

Take it to the dealer. That is mercurys DFI system same as the optimax they don't sound like that. Lot of videos on you tube with that motor running doesn't sound like yours.

Try to find the exact spot of noise, I have seen a stethoscope at HF tools if you don't have one.

Does your motor have a computer, if so get your laptop or borrow somebody's, get the software and cable,and diagnose the problem,log maintance,

Do not go into the computer if it is under warranty that could void it. The software ,cable and the computer will cost you much more than the service call. The system may be mercurys but it's adapted to a tohatsu motor.

The noise could be from conveyor, belt, bearing that drives the compressor.

Happy Boating

I have the same motor and mine makes that same noise. Also a 2012 model but with a couple hundred hours. Didn't notice the noise until after break-in.

I sent the video to another Tohatsu dealer who sent it in to Tohatsu in Texas. They said not to worry, that is the air regulator popping off while idling. He has a strong air pump with really good output. No issue with that motor at all. As it breaks in and wears some it may go down but it is not an issue. I printed the response and put it in my warranty book.
