MILWAUKEE, WI (WTAQ) - The high-speed car ferry across Lake Michigan says it's planning some changes in 2012 -- most notably, a full year of service. The Lake Express Ferry started three weeks late this season due to engine problems -- and more engine trouble shut down the facility in parts of July and August, during the peak summer season. Two of the ferry's four engines were rebuilt last year, and those are the ones which had trouble. The ferry carries people and vehicles across Lake Michigan from Milwaukee to Muskegon Michigan. It's about a two-and-a-half hour trip each way. The Muskegon Chronicle says the ferry is planning better customer service -- plus small changes to its schedule, pricing, and marketing. Company president Ken Szallai said the ferry was having an improved season without the shutdowns. The company does not release passenger counts or financial results. Szallai says the ferry's ninth season is due to begin next April 27th, and run through early November. But those dates are not set in stone yet.
