There is a mention of powerboat in Mahabharata –
सर्ववातसहां नावं यंत्रयुक्तां पताकिनीम् ||
A boat with engines & flags, capable of withstanding winds.
“Sent by Vidura unto them, he showed the Pandavas on the sacred banks of the Ganga, a boat with engines and flags, constructed by trusted artificers and capable of withstanding wind and wave and endued with the speed of the tempest or of thought.”
Interestingly Varuna is attributed to the ocean and voyages. He also has constructed his own boat.
