gauge should be on the water pump the ECM should be in the head (car)

The sensor I replaced is for the guage for sure. It does seem to me that sensor will always read a colder temp than the ECM sensor. Not sure why they chose to have those sensors where they are because they will never read the same water temp IMO. The boat runs perfect. I will take a infrared temp gun out with me next time to check various engine temps in various locations on the engine. Maybe some other LT-1 owners can see if their guage sensor is in the same spot, and post what your engine temp is when running the boat. Stx221, nice to know you're running 140 all the time....sounds about right for guage reading. I bet the actual engine temp is closer to 160 because of the top t-stat. Perfect temp.

Posted a reply awhile back in your other thread in the electrical section. My '94 LT1 has the ECM sensor in the same place as yours but my temp gauge sensor is on port side engine head. My engine temp reads around 140 unless I run hard for awhile then it climbs up to 160 and levels off.

If you have a pic of it that would be nice too. ![]() So do you also have a temp sensor in the mixer like mine, or nothing there?

There's nothing in the mixer. Here's a pic of the head with the sensor removed. I don't have one handy that shows it in place and the boat is up North. There's also a pic of the sensor itself. Not sure if this is a standard location either.

Here's one of the engine. The sensor wire is laying on the carpet as I was trying to figure out my temp problems.

Mine is normally 140 ... 160 after running hard as well.

Now that the lake temp is warming up, the engine seems to get up to 160 faster. It holds there pretty well so things seem to have stabilized.

I have not had the boat out for a few weeks so I did not get a chance to test the actual engine temp with an infrared temp gun.
