Hey guys, I'm in the process of purchasing an old sea doo jetski. Everything was great when I took it out. Later on we made a deal, and we agreed he would install a new wear ring if he got to use it one more weekend with family. He installed the ring and we he took it out yesterday he said there was major power loss and he can't figure out what's causing it. Anyone have ideas? He's going to check cylinder pressure today. Please let me know! Thank you!
