Welcome to the new Wizard Outboard Forum.
I need to replace the seals in the lower unit of my powermatic 12. Are these the same seals the same seals used in the merc Mark 25?
I am pretty sure that the Powermatic 12 shares the same lower unit with the Mark 15/20/25. I'd recommend calling East Coast Marine and double checking that the seals are the same before spending the money.
Thank you so much!
