[QUOTE="Ride_Klein, post: 227728, member: 6976"] Got a little more work on the engine done tonight. Mostly cleaned things up and should be ready to assemble this weekend. [ATTACH type="full" alt="Seadoo 787 - Crankcase.jpg"]29847._xfImport[/ATTACH] Crankcase halves apart. Some minor scoring but everything else looked to be pretty good. [ATTACH type="full" alt="Seadoo 787 - New Crankshaft.jpg"]29848._xfImport[/ATTACH] New Crankshaft from WSM. This comes complete with bearings, rods, and seals. [ATTACH type="full" alt="Seadoo 787 - Counterbalance.jpg"]29849._xfImport[/ATTACH] New Counterbalance. [ATTACH type="full" alt="Seadoo 787 - Cylinder measurement.jpg"]29850._xfImport[/ATTACH] Measurement on the cylinders. All of them were within a tenth. I believe a 1mm over piston will work. Anybody think differently? [ATTACH type="full" alt="Seadoo 787 - New Pistons.jpg"]29851._xfImport[/ATTACH] New WSM Pistons. These are 1mm over pistons and as I mentioned above, I believe they will work. If somebody disagrees please correct me. [ATTACH type="full" alt="Seadoo 787 - Cylinder Hone.jpg"]29852._xfImport[/ATTACH] Both cylinders had surface markings on them. The mag cylinder is worse than the PTO. Are the markings shown in this picture acceptable? If they aren't any suggestions on removing them without taking too much more of the cylinder wall with it? [ATTACH type="full" alt="Seadoo 787 - Crank Counterbalance alignment.jpg"]29853._xfImport[/ATTACH] Does the alignment of the crank and counterbalance look correct here? All in all a good night in the garage. A friend of mine also donated some "scrap" aluminum road signs to the project. Looks like I'll have enough to do the floor area. Will be nice not to worry about wood down there. [/QUOTE]
