Most of the Marina's have 89 octane, as that is what most I/O call for.....

Although running the 89 octane probably will not cause you any issues, you may find that when you drop back to 87 the engine doesn't behave anymore... In short once you start running 89 octane you are likely stuck doing so...
Additionally contact Mercury and make sure the running a higher octane doesn't void you warranty....

On the flip side, do you have the ability to bring gas to the boat, or take the boat to a gas station once in a while... Being able to run 87 octane, and get it at a regular gas station could save you $$$$...
