Which gauge?

I'm removing an older Mariner and installing an HPDI Yamaha. I have an analog tach trim and fuel gauge that I want to use. I am not concerned with the speedometor. I want to install a digital yamaha gauge that will show the warnings, I would also like it to show the fuel consumption. I also want to install a water pressure gauge, should I install an analog gauge, or will the digital show that also?


Which digital gauge should I buy? Its an 06 225 HPDI


Thanks

There are two kits available for the 06 motors.
6YR-W0035-E2-00 Multifunction tach kit, displays tach trim, hour meter and warning indicators. Includes wiring harness.
6YR-WE035-J0-00 Multifuction Tach and Speed/Fuel combo kit, has same tach plus a speedo/fuel management gauge, displays speed, fuel comsumption, fuel level gauge, trip meter.
Or you can use the Multifunction Fuel management kit(needs to connected to Yamaha speedo or GPS for calculations) 6Y5-W0088-54-00
Water pressure gauge is 6Y5-83660-10-00(analog) and will need 688-83667-00-00 Pressure sender.
