FOND DU LAC, WI-Mercury Marine won overwhelming approval from the Fond du Lac County Board on Wednesday night for a $50 million, publicly financed loan-a key incentive in what appears will be a successful effort to keep the big employer in town. The outboard-motor manufacturer won't have to repay about $9 million of the low-interest loan if it maintains its current local workforce for 12 years. If the company adds employees, millions more could be forgiven. MORE
