Can be a bi&&h to remove old ones.
Had to drill into old ones to make an indentation so I could take a mallet and large screwdriver and hammer it to loosen them up enough to twist them out. I used lots of PB Blaster also.

Gone in 2 months alt water
Well last year i bought Zinc only for salt water lasted the season 6 months.. This guy said Aluminum will last longer. Heck no it doesn`t. Time to get the diving mask on what a waster of money. Get only ZINC for SALT end of story. and yes my boat is grounded properly and is on a Mooring not a dock.
