So took my seadoo to the lake broke it in properly,then took it out again got halfway across the lake and it just slowed down.I noticed a lot of water so I idled it back to shore barely and drained the water. Then put it in again and noticed it had little thrust would t go over 5 mph. Then noticed again a lot of water,then drained it and noticed the driveshaft was leaking.Did research the carbon ring was leaking.thus filling the hull with water.Is the the carbon ring related to thrust issues?
