This may be a dumb question, but I just bought a 2018 with the new G2, and all my lowrance units are nema 200 linked, so when running, on my right screen I run all my gauges, and I watch my water pressure from there, I have never noticed where the the piss hole is on these motor's. Is it directly in the back under the exhaust in the port that you screw your fresh water hose for flushing the motor? I looked all over the manual and cant find anything.
