The crankshaft is installed in the top of the crankcase to align the grease holes for the magneto bearing. in the video you did not do this and your bearing was left without lubrication.
if it is getting into both it could be a warped cracked head or gasket. exhaust also could be the cause. did you check the rubber coupling around the exhaust? I think i would start there. I think i would then fill with water in the cooling passages and start it to see if you are getting air bubbles. with the rubber coupling off and go from there.
Mike Kisch Thanks so much Mike for replying Yes both cylinders when I did the engine flush it got worse and motor stalled will still run but when I flush soon after stalls the stops remove plugs turnover motor water in cylinders again do in expecting exhaust fault just don’t know were to start don’t wanna pull engine apart if simple fix

Where are you getting your Yamaha wave runner engine parts ?
ebay or online parts stores.
Where did you find the engine specs your referencing?
Service repair manual. I usually get a pdf file online.
Great job but wrong case sealant and way too much used. Use a thin anaerobic sealant.
😃👏🏻👏🏻
I just know you were dying to say schematic at one point during this teardown; don't worry we can take it.
