Found a company. Clean Fuels in Annapolis. They will come to your boat. It is $300.00 for the service plus $2.00 a gallon. If you take your boat to them it is $250.00 plus $2.00 a gallon. Their phone number is 1-800-453-8265 in case you want to jot it down in the event you may need their service.
I had another quote of $6.00 a gallon plus amt. for time it takes to pump it out. This was taking the boat to the place.
