Part of the reason for this is that English didn't even exist until fairly recently (though still before modern times). But there were various Germanic languages, some of which English evolved from. There are a fair number of Spanish words of Germanic origin, some fairly old, perhaps dating from the Visigothic kingdoms in Iberia: guerra, guante, rico, orgullo, arpa, blanco, banco, frasco, yelmo, flecha, emboscar, jardín, flotar, bisonte, etc.

More specifically with respect to English, though, https://en.wikipedia.org/wiki/List_of_Spanish_words_of_Germa... says that bote comes from Old English "bāt" via Middle English "boot" and then Old French "bot". The other words in that category include arlequín, este, norte, oeste, and sur/sud-. But when did those words make the jump into Spanish? Some, like arlequín, were fairly recent!

"Old French" was supposedly spoken up to the mid-14th century, so words that came into Spanish directly from Old French probably came in before 01375 CE. But there's always the possibility that the word lingered for a century or three in some intermediate dialect like Occitan or Catalan before making it into Spanish. Unfortunately I don't know of any resource in Spanish comparable to the OED or Etymonline to find old Spanish attestations.
