    Help Needed III

    So I'm out running the #2 ski that I haven't rehabed yet (#1 recently apart for fuel pump/fuel issue, exhaust gaskets/filter, SC belt replacement, and jet pump rebuild). Thing was running great then just bogged down and died, restarted a couple times but would not run. Had to be towed into dock by #1 ski. I get it on trailer and in garage and it still won't start, just a loud click and crankshaft trying to turn but can't/won't turn engine over. So I'm thinking maybe the pump is frozen up like the #1 ski did (impeller frozen to wear ring) as these skis are identical/been ridden, stored, maintained exactly the same. So I take off pump and it's fine; impeller turns easily with one finger. Next thing I'm thinking is maybe the SC is locked up. So I take all that stuff out of the way and compress the belt tensioner/put clamp on spring, still no luck with SC belt loose. I have new batteries in both skis but just to be sure I bring truck around and try to jump start it, exactly same. Loud click, crank trying to turn nada. So now I figure must be the starter, so I stick a screwdriver down in the coupler and find that the crank will rotate. I rotate it a 1/4 turn or so, try to start it and bam it turns over and starts, but still won't stay running.

    Btw never got any code on the instrument panel. So now I'm stumped:
    Don't think it's the starter cause it started the engine (oil looked normal)
    Not the SC
    Not the pump
    Not the battery

    What would be the next logical thing to check? Timing chain or cams or what?
    Any help would be appreciated greatly!

    Well you checked the pump, but was the impeller all the way on tight? Any fore and aft play in it? If it came loose, moved forward and destroyed the thrust beating on the crank is a possibility.
    Compression check in order, how do the spark plugs look? Any damage? No water on them.
    Will it turn over with the spark plugs out?

    Ah same ideas at same time!

    Plugs 1, 2, 3 looked fine. Pic of #4 below. Impeller is on tight/correct measurement from case end to impeller end (<.4 ish inches). I guess I'll be pulling the head next to see what's down there and see if all the pistons move when you turn the crank. Yesterday I turned the crank by hand and both cams move, so I guess that's good. What's bad is the crank turns maybe a 1/4 turn in the ccw direction then feels like it's coming up against something solid. Like it won't turn any farther, the long screwdriver I'm using in the coupler would bend/break before it moves anymore.
