Oddball question: While detailing my new to me 2006 185 Sport earlier this evening I noticed that the bottom 1/3 of the hull from the transom to the center of the boat is a light brown in color, however only on the starboard side. I'm assuming it's from a water stain although this doesn't explain why it's only one one side of the hull. Perhaps only 1/2 the hull was cleaned before winter storage. I have tried 3M marine cleaner/wax which I am using on the rest of the hull which will remove it with a fair amount of elbow grease. Any other thoughts as to what it might be?
Thanks.
Thanks.
