There is a big stock of 2 stroke yamahas and suzukis 25-30 and 40hp in prices ranging from 1250 to 1550 eur in the South of Spain.
They come from the Zodiacs that illegal inmigrants use to reach Almeria's shores along the year so they've been used for just 8 hours.
Today I got myself a Bombard C5 and a Yamaha enduro 40hp for 2800 both in a fairly new shape.
They will provide you with documentation.
Here's the number of the guy who sells them +34 665126388 (pablo), he does sell abroad and I believe he speaks English.
Good luck (and get yourself a 40hp!).
ps: you can also look it up on the internet in Spanish
