Low Temp reading / 454 Mag MPI
My temp usually runs about 170. Yesterday my gauge would not read over 150 even after running for miles. I was thinking of going ahead and replacing the coolant temp sensor and the thermostat. Those two parts are cheap. This motor has 520 hours on it and seem to be running fine. Does it sound like I am on the right track?

Re: Low Temp reading / 454 Mag MPI
Hey Mike,
I'd like to be making more power but I think I am getting a false reading on my gauge. Plus I think the MPI motors will run too rich if the temp is too low. I didn't notice any soot on my transom. Thats why I think it could be a bad temp sender. I was just looking for an expert opinion here.
Thanks,
Dave
