i believe so, that looks to be a normal amount of carbon seal residue . older models had a shield containing the mess from the seal , leaving it unnoticed . unfortunately
seadoo get cheap no shield. keep an eye on the seal itself measurement size . it is a wear item .i think it is something that should also be looked at once in awhile when ski is in water running ,to make sure you dont have a large leak. i believe they all leak a little when running and under speed the pressure is great.. of course many will disagree, just my experience and 2 cent
