The ground cable from the lower tray to the powerhead is on the left, with the battery ground to the right of the choke solenoid. I went back to the early pic 7 years ago, just to check (I once had a 45hp magento motor that had a ground cable directly to the block. The 55hp appears to be a workaround given the 2 external coils, mounting bracket and the regulator – I did think of mounting it to the starter motor bolts, but it’s kind of crowded…).
