Lowrance 1 - 2 amps ?
MP3 Check it's recommended fuse rating and subtract about 30% for actual max current. 6 amps ?
Nav light (24watt ?) 2 amps
Light bars Depends on the rating. Theory divide wattage by 12 to get amps but I'd guarantee it'll be less. 3 amps ?
Charging iphone......not worth counting but you might want to plug something else in there.......spot light ? (that'd be about 5 amps)
LED gauges 1 amp ?
Your engine 90hp 2 stroke 2010. Stator charging (no alternator) maybe 15 -20 amps
All guess work but that's probably the sort of figures you're dealing with.
