Never saw a 32 amp fuse. Next -- none of the three devices you mention can use a 3A fuse without it blowing on start-up. As I mentioned, the trolling motor should not be wired through the fuse panel. It should have a separate fuse in the hot lead close to the battery. If the troller is 30# thrust or greater it can draw as much as 42 amps so again, none of those fuses would handle that current. Although the 20 and 30 amp fuses will hold up for the livewell and bilge pump, they are very likely too big for the wires feeding those devices. That means the wires would smoke before the fuse blew. You really need to determine what is on each circuit. 10A fuses max on 16 gauge circuits, 15 amp on 14 gauge and 20 amps on 12 gauge.
