Hi Folks,
I've been impressed with my 356 and the engineering involved. But, I do have one problem. The thru-hull for the engine water inlet is slowly corroding.
The other thru-hulls are bonded to a submerged zinc mounted in the hull. They show no signs of corrosion. But, the engine water inlet thru-hull is bonded via a long, circuitously running wire to, I believe the lead keel. As I understand the galvanic series, that's not a good way to prevent corrosion on the thru-hull.
I'm considering removing that long circuitous wire and bonding the engine water inlet to the zinc mounted in the hull. But, I'm reluctant to modify what I've seen as a very solid engineering job. How are other's Hunter 356 thru-hulls bonded?
Thanks for the help,
John
