If the engine has been driven hard or there have been engine problems that have caused it, you might have plug problems. OR, maybe the mechanic just needs to make a boat payment. Try another mechanic for verification.

If it has the correct plugs in it they should last the 100000 miles. So no that is not good advise. Now that being said I have seen bad fuel cause plug problems. I have also seen wrong plugs from the factory, like the engine calls for platinum plugs but it had copper ones in it. It is definitely worth a second opinion.
