I have a 798 CI SI.
 I put it on my kayak and I have about 8 foot of wiring from the battery to my unit. I used 22 gauge wiring because it was close to the same size as the power cable that came with the unit, it looked like it to me.  I have the inline 3 amp fuse, I also have a mercury tilt switch in line also, just in case I were to turn over, to keep it from shorting out.
I have read some of the discussions on this forum about wiring for units.  It has got me confused and concerned now.  My question is the wiring that I used OK?  Or do I need bigger wiring.  I have nothing else connected so interference shouldn't be a problem.  My battery is an 8 amp hour battery.
