I had a leak and bought these gaskets for my starfish. The seals fit well, there were no leaks. After about a month, I noticed that my steering wheel was becoming harder and harder to turn. I took the boat to the mechanic and he told me the seals were wrong. I compare it to my starfish number but he said he's never seen green seals for that specific purpose. $250 later for installing new Sea Star seals, hydraulic fluid and labor. I think OEM parts are better than no names.
