96 Mercury 200efi, had it for 9 months now, when purchased idle pressure was about 2lbs, wot was about 8lbs. Replaced complete water pump, thermostats and poppet valve. Idle pressure is about the same , wot is a little better but I think still too low at about 12lbs. I am about to install the mercury high speed inlet kit, but my question is this. Currently the pressure guage is plugged in inside the lower unit, if I plug it off in the lower unit and tap it into the crossover hose between the heads would that give a more accurate reading or no ? Thank you for any info.
