I have had my boat for just over a year,@90 hrs on 2006 ETEC 75. Recently I smelled exhaust? really bad and noticed alot of oil in the water under the boat at the ramp. Thinking this was just the remains of a busy day in florida, I thought nothing of it. Gettin home, I had wondered lately about rough idling and pulled the engine cowling to see if anything was obviously wrong with the spark plugs,etc. To my surprise the oil tank was almost empty and I hadn't run the boat 3-4 hrs since last filling it up. I did notice just below the top a small slash in the tank you could see went through. I filled the tank to just below this line and marked it with tape, the next morning it was about 1-1/2 inches below the tape. Obviously another leak in the plastic tank. Anyone else had these leaks or cracks in the oil tanks? Took the boat to the closest evinrude dealer where it has sat for 2 weeks(****** about that). Anyone had any rough idling problems? How about condensation in the gauges?
