No, just pull the bolts on the cav plate and exhaust and pull er off.

Don't forget to coat the shaft splines and shaft itself with a good quality marine grease to prevent corrosion and galling.

Do the same for the bolts and torque them with a torque wrench. You are torquing stainless steel bolts into aluminum and you don't want to strip the threads or snap off a bolt.

Re: removing lower unit

If you have a water leak you should check your lower unit oil by draining it. A small price to pay now to avoid an expensive repair down the road. But yes you should be able to remove the lower unit with out draining it.
