Boat with the 225 is rack stored and never left in water. '03 with less than 400 total hours. Run into salt water butreturn to marina on Intracoastal is brackish but nearly fresh water. Engine is fresh water flushed for 10 minutes every every use. Concern is replacement of internal anodes. If mechanic is going to inspect then would be foolish not to replace but the question is given what I stated about use of boat/motor, would it be recommended to have him proceed?
