    It is in the same spot as it is on the carbed 951.

    The starter is right under the throttle bodies (under the big plastic airbox) which is under the pipe flange on the left (as you sit on the machine) side of the engine.

    ok, the starter is just spinning without engaging the bendix or flywheel, would you lean towards the starter or the bendix?

    The bendix is the more common problem. Normally they wear the teeth down where it meshes with the gear shaft on the starter. When it hits that worn spot, no starty boaty.

    It can be done in the hull but is a pain since you have to pull the front flywheel to get the bendix out of there. I pull the engine to do it, though there is a bit more involved on a DI than a carbed 951 so choose wisely

    If teeth are missing from the bendix you will need to make sure "they are out" before you put the front cover back on. Also it would be wise to inspect the teeth on the starter as 1 can wear out the other and you will not want to replace the bendix a 2nd time on a DI because the teeth on the starter ruined your new bendix.

    I am surprised that the bendix is giving you problems on a DI because they start instantly with not much wear and tear, as they changed them from 99 onwards and for the better.

    You might consider removing the pipe to see better before starting???

    1)To remove the bendix you will have to remove the oil pump and lay this out of the way still connected to the oil lines.
    2) Support the front of the engine (usually a block of wood underneath) and remove front mount bolt and front cover bolts.
    3) Disconnect the main wiring harness from the front cover and remove from craft.
    4) You will need a flywheel puller and remove the flywheel to gain access to the bendix.Dont loose the keyway key from the front of the crankshaft .
    5) Remove the plastic support plate bolts and then the support plate (careful you don't loose the spring inside the support plate.)
    6)Remove the bendix and inspect.
    7)Re install in the reverse order but when i install flywheel I heat this up in a pot of boiling water before for 5 minutes and then quickly bolt on in position and torque the nut ,this way the flywheel shrinks over the crank and will never move. hope this helps.

    The solenoid stuck and forced the starter to keep engaging. We were riding when this happened so it took me a minute to get the battery cable of the battery, so Im concerned there's going to be damage

    The bendix has a run on clutch feature so when the engine starts it runs on with the flywheel and then the spring pulls it back out of the way. With your situation it seems like it couldn't disengage properly so you could have some damage in the front of the engine.
    Either way you will need to pull the front cover and flywheel off completely to inspect for damage,You may have 1)teeth missing on the bendix 2)starter motor shaft damaged 3)the bendix clutch damaged 4)ignition sensor assembly damaged. If you have any iron filings floating around in the front hub area these will be sucked onto the magnet and this usually short's out the fuse in the MPEM. Did you get it started again trying to get back to the ramp ??
    If it was mine I would pull and inspect to have peace of mind.Oh and replace the solenoid.
