    It may just be the picture, but it looks like the lower unit is cracked.

    That ain’t normal, just got mine out of the shop for a blown seal. I had water in the gear case. Better get it to the dealer.

    Mine (a 2019 225 pro XS) looked like that…not saying it will be for you but for me it was a blown carrier. Get it to the dealer.
