I do not like the way they installed the water pressure gauge or where they get the reading from. They just t'd off of the tattle tail hose. Where is the best place to get a GOOD H2O reading from on these engines. I have always mounted up high on Mercurys because thats the last place for water to get or the hardest place for cooling water to get. Could someone please explain a better place for mine. I am now replacing my reg/rect again becasue of low pressure on top. Thanks in advance.
