Since about 2015 Bass Cat has had a separate harness for graphs and power. The older boats had 6 gauge to the console where a brass terminal block exists, and we connect 10 gauge to the bow. All connections in that harness are soldered with fine high grade tinned wire to reduce corrosion.
About 2021 we shifted to 6 gauge and 6 gauge with terminal blocks at both the front and console.
On Newer 2023 boats we upgraded those connections and corrected a terminal issue we found.
Voltage Drop when starting:
We have one to add, if you are finding the ignition (starting) knocks power too low for graph operation, then we suggest a small copper washer (2023 standard item) on both terminal posts bases. Apparently over time the terminal lugs become incompatible with the Mercury bronze buss bar all the wires gather on at both terminal posts. The small copper washers against the terminal lugs resolved this issue.
