No. The prehistoric Indo-Europeans appear to have had no words for the ocean, or ships, or other such things. Or if they did have words for these things, their descendant cultures did not inherit them. This, and many other clues, suggest they originated on the central Eurasian plains. Don't need a word for ocean if you've never seen one.
The Germanic languages are a branch of Indo-European, and this offshoot shares common words for those sea-related things, and also words for many dozens of species of plants and animals (all the tree species, for example, native to the region.) These words have similar properties, and were almost certainly borrowed from an earlier, unrelated culture already living there.
The Basque today speak a language, that, before Roman times, seems to have been spoken all across Spain; it's probably the only remaining relic of what was once hundreds of distinct cultures that existed in Europe, in the neolithic era, before the Indo-Europeans.

I don't think that a piece of land the size of the Iberic Penninsula could have spoken a single language in prehistory. Even in the modern day, in places that didn't have a concerted effort to impose a single language, we see a huge diversity. Dagestan for example has 14 different official languages, in a region with 3 million people, and an area almost half the size of Portugal.
Even in the Italian peninsula in the times of Caesar, there were at least 4 major languages spoken - Latin, Umbrian, Venetic, and Etruscan (which is not even indo-European).
