I read in another posting that Seadoo snipe and others had some ideas to align the engine without the special tool. I would love any advice for alignment without the tool as I live in an area where shipping outcosts the tool price. Thanks for your help

Thanks ocod, I'm weighing the options of sending it back to them or tearing it apart. It seems that shipping to where I am is outrageous so I might just have to do a cleaning of the bottom and top end rebuild (boring out the cylinders if possible). You know anything about the sizing of the...

light scoring I opened the engine removed the head, cylinders, and pistons. The bad piston exploded in there but the cylinder walls only have one area where scoring is a concern. This is a remanufactured Seadoo 717 engine from SBT. Is there any way for me to know if the cylinders have been...
