If you have acces to a hoist or Chainfall you could attach the bolts to the heads and take the weight off of the mounts. This should provide you enough releif of tension to replace the mounts one at a time. This is of course provided that you can get to the mount bolts with the engine still in the boat.
You could possibly do this a number of ways with a small jack since you arent fighting the suspension and rest of the bothers in a car.
I would disconect the input shaft from the pump and BE CAREFULL with the chainfall or you can damage your heads.

Not trying to be an ass or anything... but how do motor mounts go bad? Are you talking about stringer damage?
