Repower 225 2 strokes to 225 4 strokes

[1waterloo]

I have decided to repower a pair of 225 OX66 to 225 Yamaha 4 strokes. Can anyone let me know if all wiring harness and gauges will work on the new motors. The 2 strokes were 1998 and the 4 strokes are 2005 model years.

Thanks

the tachs may or may not work.
depends on the tach part number.
if the tach's have the 3 dip switch's your ****en.
if only 2 your going to need tachs.
if buying USED F225's have a bore scope run up the ex to check for corrosion.
