I have a 94 Mercury 200 that I have replaced the temp gauge, T stat's which do not tell me the temp range, and installed a pressure gauge yesterday. I had another temp gauge that only read from Cold to Hot not very useful I wanted to know the actual temp so after installing it and the sending unit that came with it I have an idle temp of 170 water pressure is 2psi and the pee hole water stream is what I would call week.
After seeing the temp and psi I took the Tstats out and ran it with out them. Water temp came down to 130 water psi was about 1psi and the water stream from the pee hole was fantastic, but I called a buddy and he told me not to run it like this as the water needs to run down the inside of the housing across something he called an exhaust plate. So I put it all back like factory. Obviously the temp came back to 170 and psi stayed at about 2psi.
So then I clamped off the rubber water hose that travels from the center top of the engine down to the bottom of the block to something I think it is a poppet valve not really sure. This brought my psi up to 10 psi where I think it should be. water stream from pee hole is still weak.
What should the temp be at idle?
What should the psi be at idle?
What is a poppet valve and do I need it?
Where do I start looking from here?
I know these are alot of questions But I figure the more I ask the more I learn.
Thanks in advance for your intelligent feedback.
