We have a 2000 B3 and to date haven't seen any abnormal corrosion. (knock on wood, err, gelcoat) I believe most, though not all, complaints stemmed from use in salt water. The problem is real, just perhaps not so prevalent in Winni water. I would be more worried if the boat is to be left in a marina due to shore power leakage currents. I also heard that Mercruiser changed the B3 design in the later yr 2000 models to reduce the quantity of non-matching (galvanically speaking) metals. Perhaps the boat in question is one of the later versions ? Find out if you can and also use magnesium anodes ("zincs") in Winni waters. I'm as interested as you to see how B3's have fared here on the lake ... hoping that you'll get many responses (good or bad).
