    93 SL 750 Rebiuld

    Hi to everyone
    I need a little advice? I just finished rebuilding my 93 SL 750 but I think I made a #%$^ UP. I went to do my initial start up and I turned the water on to the flush hose before starting the ski I went to start it but it would not start due to bad battery. So I put a charger on it and while waiting I decided to check the plugs and thats when I noticed water in the cylinders. Now the reason why I rebuilt it was because their was a crack in the case so I welded it, bored the cylinders 1 over manuf, and installed new pistons and rings, Tested the case and it worked. Is their a way to remove all the water that filled the case?? and I noticed some threads on the forum about running the water without first starting the ski so the case doesnt fill up. IS THAT TRUE?? I hope it is because I dont want to pull the moter again. Now I know I didnt do anything to the crank or the pistons due to the battery being DEAD THANK GOD. But how do I make sure their is no water in the case?? Also on the fuel pump where can I find info on what each hook ups are on the pump and to also to verify if it is actualy working??

    What he said ^^^. And it's start engine first, then water on. Turn water off, then shut off engine.
