I have a M40D2 from 2006 and am looking to install a temp gauge. On the head there is a threaded hole for a sensor but does anyone know what thread it is?
Thanks
Hi, William
i don’t think this dt40 2 strokes has a pop it valve but will check diagrams just in case.
Since in salt water (Sydney, Australia), your corrosion point is definitely worth checking.
when replacing the Exhaust gaskets, we noticed that the top half was dry so the water was not going...
Thanks guys.
I had a second look and the plate looks very flat and no leak on the edges. This water pump casing is metal inside and is not scorched.
I tend to agree with William that the top grommet could be damaged but I was not keen to disconnect the powerhead to check this.
One additional...
The motor is running fine on muffs and it cools properly with water coming from the telltale and the exhaust when the thermostat opens, but when running it in a bucket or in the water, there is no water from the telltale and water does not reach the top of the engine and it gets very hot. I know...
