      May 23, 2018 at 6:11 pm Hello all. I just joined this forum but have been familiar with Seaboard with ordering parts for my QSM 11’s for a while. I have a small leak which appears to be at the front plate of the Valve Block. Thanks in advance for any advise or tips on getting this fixed. Is there an “O” ring kit?

      May 23, 2018 at 7:33 pm Hi Tony, Thanks for the quick response. Unfortunately, I’m now in NY and the boat is in Florida and I wont get back to her until June or July. Attached is a similiar photo from another post where I pointed to where I believe the leak is coming from. I put a piece of an oil pad and slipped it under the end cap and it became oily after running. I guess it’s possible the leak is from under the valve block?
