ST. LOUIS Mo. (KMOX) — A local tugboat company got new engines on two of its boats this week. So what’s the hullabaloo about?

They’re not just engines. They’re fuel-injected, propulsion engines and compared to the old diesel engines they’re replacing, these burn much cleaner.

St. Louis Clean Cities executive director, Kevin Hurdler, says they burn up to 60 percent cleaner and they use up to 40 percent less fuel.

The older diesel engines were swallowing up to 650 gallons of fuel a day and have no emission controls obviously reeking havoc with its big puffs of exhaust rolling into the air.

The new engines were also bought locally which is always a plus.

The engines are being installed on the two JB Marine tug boats that operate in the St. Louis harbor with the EPA  picking up a quarter of the cost.
