Installing water pressure and temperature Yamaha 85hp

[DoubleWeber]

I would like to install both water pressure and water temperature on my Yamaha 1999 A85 (aka C85 in the states).
I know where to install one of them, but I can’t figure out how to do them both.
I know of the one bolt to remove to get access to the cooling water. Is there a way to do them both together or separate?
