Nope . It needed so much power to overcome the drag in the water and actually get up in the air that it proved to be inefficient. The idea is good though.
Look up the Caspian Sea Monster. It needed the engines just to take-off. It needed less than half of that power to maintain flight once established.
EDIT: Yup.
