I finally got my boat together yesterday and when I ran it i went to set the water psi and did not build any psi at the manifold.
My set up is inlet-dump valve-headers-engine. The outlet from the thermostat divider has two 5/8 lines straight out the back of the boat.
I installed a water psi gage in the manifold and it is a 0-100psi water pressure gauge.
The engine runs at 160 and their is plenty of water running out of the t stat.
Are the 2 5/8 lines big enough so i don't need the dump valve?
If the temp is staying consistent then is everything ok with no psi in the manifold?
