Is there a good kit from mercruiser for bellows, gimbal bearing, etc for when I pull it apart?
And when running on the Trailer, and switched to prop exhaust, should all exhaust water be coming out of the prop, or should some be coming out of the upper drive housing?
missed this....
I'd slow your roll cowboy..

that's a fair bit of fockin around in a drive that may not need it..
and just a word of caution.. a bellows job is a bit convoluted if you don't know what your doing... the bellhousing needs to be removed, hinge pins, needs to be prepped right, installed in a proper sequence, yada, yada... and anywhere in that process, you moving the hanging bellhousing the wrong way, and you WILL break the oil tube, which is an utter nightmare...
when you remove the drive, you'll inspect the gimble bearing and bellows, no water inside the bellows and no dry rotting externally, and just stick your hand in there and spin the bearing back and forth with a couple fingers, you'll hear, feel it if it's bad.. when bad they'll groan at idle... if they are good, generally ya leave them, unless there is history..known water anywhere, dry rot on the bellows, etc.... there is a grease zerc on the side of the drive for the gimble bearing before reinstall...
throw in, there are about 5 merc specific tools in those jobs there that you WILL need... pretty specific gimble bearing puller, alignment bar, bellows driver, bearing driver, etc... which can add up...
now.. on that note, the real question as to whether you need to venture into the transom assembly, outside of water infiltration, is this, does the boat have a trim gauge (I'm assuming it does), if so does it work?
if not, you more than likely need puck work......
oh, wood cradle for drive storage out of 2" x 8" or 12" .. 2 a skegs width apart, than a couple perpendicular at the ends.. like 2' x 2' footprint.. watch the shift cable if you pull that drive without a yard arm.. easy enough, just gotta know what to expect or it could get hurt from the weight...
oh, sorry missed the exhaust question... you more than likely have a failed exhaust bellows, which sits right below the main, joint bellows... while annoying, it's not really a critical failure per se, plenty of boats running around with bad exhaust bellows...

there are 2 styles, clamp at both ends (pain in the arse), or slip-in style.. not sure what that'll have off the top of the head.. i could look it up from that drive # if i had a minute at work... it'll be obvious tho... if it's the clamp at both end, you need a special tool, slip-on is just hose clamps and simple...
i see it has a shower head..
