If I swap one out only one of my twin application 1997 BF90A with a 2007 BF90DKXRTA, do i only need to swap out the wire harness? Can I keep the key switch and gauges?

In assume the hours on a 2007 are read from the ECU so one can't forge the amount of hours?
 
Key switch, gauges, and wiring harness will all work with the newer motor. Since the newer motor is fuel injected, you will not have to choke the engine or advance the throttle to start the engine and .... there are two additional warning lights that would be good to have....check engine and charge lights (PGM-FI). You can add it with a small wiring harness and light panel. The 9 wire PGM-fiharness (various lengths on this Honda web site page http://marine.honda.com/outboards/accessories/harnesses[h=2]PGM-FI 9 Wire Panel Harnesses[/h]

BF40D-BF25032340-ZW7-000AH

Should be used if not using key switch panel 36452-ZW7-100AH/AHR or 36652-ZW7-100AH/AHR. Includes 3 foot harness. 1 panel per engine.

and yes the ECM stores the number of hours.

Hope that helps.

Ha, this helps a lot and you may have just cost me $! Was not expecting this answer at all,
but I like it!

So all the work will be hanging and connecting the motor, "plug and play you say"....Cool !

I fully understand the idiot light add on, great option.

Thanks Mike!
