How do you disconnect the drive line in a 1996 seadoo spx?

there is a round drive flywheel that bolts to the crank shaft of the motor. the drive coupler then bolts to this bombardier usually use allen sockect head screws. this also has the splines that connect to the impellor shaft. remove the shroud and then remove the bolts you then can slide the coupler back onto the shaft enough to remove the engine or disconect the drive. the shaft is then pulled out of the rear(after impellor hsng is removed)
