    look in the back of the jet nozzle,does impeller spin nice and freely,what happens is the pump liner is stainless steel and housing is alloy and the alloy can corrode and push wear ring into the impeller and seize it

    these skis all all similar in design - the 1200 service manual will at least shoe you the theory

    to get the 2nd small shaft out you have to move the engine forward about 1 inch so you have to undo the motor mounts and disconnect the exhaust from the waterbox

    next you will see there are several bolts that holds the housing connected to the small shaft to the transom - these bolts have to come off
