? about bonding fuel tanks

[Fr. Frank]

The fuel fill neck should be grounded separately from the tank ground. Both should be well grounded to the battery.

I also have an 8"x3" bronze grounding plate on my hull which provides over 12 square feet of grounding surface area in contact with the seawater. Since my zincs, motor, and electronics are also grounded to this plate, it really helps eliminate any electrolysis from happening apart from the zincs.

In case of a lightning strike or near strike, the grounding plate can save your motor and communication electronics. You can buy them for around $70 to $100.
