I have a 93 Lund Tyee 1850 I was working on and hit a hot wire to the hull and got a spark. I don't know if the hull is supposed to be grounded, or getting grounded from the motor being bolted on, or I have a problem somewhere?
Thanks for any help.

Ayuh,..... The hull needs to be Bonded, but you don't run a ground circuit through the hull,.....

So,..... Yes, the spark is normal,.....

Yes, an aluminum boat will have ground through it. But don't attach grounds to the boat itself or it will cause electrolysis
