I have my EGT preturbo. How long before I should look to replace it. I tow #6500 boat in the summer. My guess would be 2 years.

 

Mine has been in place for 5 years now with no issues.

 

Let me guess, someone told you it will break off and go thru the turbo, causing destruction of the turbo? Thats a story that's told on some of the other forums, but ask anyone if they know anybody that actually happened to...

 

Ask in the 1st generation forum.Bet some of them been in a long time and MANY miles.

 

3 years and counting....

 

We put the same probes into aircraft pre-turbo if that tells you anything. Probes breaking off are extremely rare.

 

Don't sweat it - a deer will jump through your windshield far more often than your probe will fail...

 

I do not believe it will fall into the turbo. I work with heat treat equipment and some customers will change the thermocouple every year. It is pretty cheap insurance and maintains accuracy. With the temperature variations, I would think the t/c would get inaccurate after a while. But if you folks have benn using it for 3-5 years, I'm not going to think about it for a while. I should just watch TV and quit thinking too much.

 

It's a good question, and you are right. Heat treating metal needs to be at specific temps for a specific period of time. We use the probes to just monitor trends.

Put the remote down and post away my friend.
