If it came from the factory with a mechanical fuel pump, I would go back with the same pump. I wouldn't switchover to an electric due to potential legal issues--if the boat ever blew up. The marine engine bay is different from that of an automobile under the hood.

The Mercruiser pumps are very long lasting.
