Try filling in more of the item specifics - the listings appearing above yours have far more filled in like "Model", "Country of Manufacture", "Colour" etc.
The "Boost" link is to promote the listing; i.e. the listing will appear higher in "Best match" results, in the "Similar items" section of other people's listings in return for paying a promotion fee when the item sells. There are not that many of what you're selling available so I wouldn't bother promoting it if I was you.
Give me ambiguity or give me something else.
