ROCHESTER, N.Y. (AP) – A new snag has surfaced in the relaunch of a 55-mph car ferry that plied Lake Ontario for just 11 weeks before getting swamped in debt: The engines need a major overhaul.

The Rochester Ferry Corp., a city agency that bought the Spirit of Ontario for $32 million at an auction last month, said the German engine manufacturer recommended repairs before the ferry resumes daily voyages in May between Rochester and Toronto.

The maintenance work could cost as much as $2 million, but it is unlikely to delay the scheduled relaunch on Memorial Day, officials said.

Last year’s maiden voyage was postponed for two months after the Australian-built ferry sideswiped a pier while docking in New York City on April 1. It later had to undergo a $1 million engine overhaul.

The five-story-tall ferry, which can load 774 passengers and 220 cars, sailed for 80 days before its private owner, Canadian American Transportation Systems, abruptly suspended twice-a-day roundtrip crossings on Sept. 7 with $1.7 million in debt.

Unable to woo private investors, the city of Rochester instead created a limited liability company to buy and run the ferry, which crossed the lake in 2 hours, 15 minutes. The 171-mile road trip to Toronto usually takes three to four hours.
