Ok you Seadoo guys, I just bought a 951 from a guy and I know yall talk about disconnecting the silenoed valve from the rave valves and just running a hose to connect the two. My question is does this hurt the performance of the rave valve and the one I bought has a screw stuck in the the outside fitting were the tubing line connects too. Do I need to take this screw out and do I need to find a silenoed valve for this ski? Any comments will be a big help.
