I have an 84' Proline with Johnson 90 hp OB.<br /><br />It ran fine all summer until I was cruising along and the boat began to bog down. I noticed what looks like dirt in the fuel filter. I flushed all of the gas out but the filter still has these particles in it. a friend said that I need to "steam clean the tank or have it cleaned" The only access to the tank is through small hole in the floor. I have a steel tank and do not know what to do short off cutting a hole in the floor to pull the tank. any suggestions are greatly appreciated.
