I have recently tried installing a water pressure gauge on my 2010 Yamaha 90 hp Four Stroke. I am only getting 2 psi at WOT. I can't seem to figure out where to connect it to the motor. I spliced into a line on the starboard side of the motor with a brass T-connentor thinking this would do. Nope.
If someone could point me in the right direction on this, I would be forever grateful. My pride is a bit stung here.
