There may also a manual release valve on the pump, that allows you to lift the drive without disconnecting the cylinders.  Unfortunately, I do not have a picture of the release valve, but I had done that before on my previous OMC Cobra.  
Still requires a ratchet strap or a strong guy to lift, but when the valve is screwed closed again, the drive will stay up on it's own.
