    Default new sbt seadoo 587 engine will not turn over with spark plugs in

    i purchased a rebuilt seadoo 587 yellow engine from sbt i installed the engine and set the rotary valve like the manual instructed but it will not turn over with the sparks plugs in but turns over fine after i remove the spark plugs. Any thoughts other than a bad starter.

    You want it get it on the motor case itself. A nice solid metal ground.

    one more thing when i installed the rotary valve i put the 360 degree mark at the bottom of the mag port with the mag cyclinder at tdc and marked the 130 degree on the case witch was right on the mark on the case so when i installed the rotary valve this put the bottom edge of the rotary valve right on the edge of the bottom of the mag port not a 1/2 inch away like i saw in a thread that bill o'neil sent out so is this correct

    What ski do you have? I believe your rotary valve should have a 147 degree cutout. The only way what you described could happen is if you have the wrong valve, a 130. THis however has nothing to do with your starting problem. Read the tech article on hard starting.

    Frankey, 18-20 degrees ? Where did that come from ? he is not setting the ignition timing.........

    The old 587 engines use a 130 degree Rotary Valve. The top edge Valve should be about at the pointer mark on the case with the mag piston at TDC.

    Do not confuse my postings about 147 and 152 degree valves with settings for 130 degree valves. They do not sit in the exact same places as each other. That is why they make degree wheels and service manuals.

    I think I confused a couple threads - I could have sworn this one said he had a 1992 ski.

    Anyway, yes you should have a 130 cutout valve, and you should time it to 115. There is a tech article that lists all this.
