Alaska’s Marine Highway System wants a court to order the fast-ferry builder to provide new engines for the ships. State officials say engines on the Fairweather and Chenega are wearing out far faster than their warranties promised. Replacing the eight engines could cost in the range of $20 million. The state filed a lawsuit last year, but continued talking to the manufacturer about a solution. Captain Mike Neussl says the state is now asking the court for a preliminary injunction to force action before the engines wear out.
