If your motor is no good to resell for some good valued money than your not at a loss that is the key to strip the motor your self, repairing outboards becomes costly and ineffective when u pay a shop to do the work they charge $110 per hour they actually charge $110 to remove 1 broken bolt believe it and yes u will likely snap a bolt i actually snapped around 20 bolts on one exhaust plate
a welder is your friend
mark everything put everything in zip lock bags and mark it as it comes off the block even if its just 1 bolt write down where it goes
number your pistons and conrods to allocated positions unless u decide to install all new
if u have a Johnson or Evinrude it gets a tad bit more complicated on a rebuild you will need to use plasti gauges to measure your shell bearing clearance
if you go a head take pictures if u have questions ask on this forum plenty of helpful people on here combined is a wealth of knowledge if you don't know the answer its likely someone else does or has encountered the same thing
