If it were me I would wait. As someone else said here, it is a buyers market, so why buy something that doesn't fulfull what you need ( and with a 25HP engine it won't ).
When I bought Neo it has a "dodgy" engine which never really went quite right - expensive to service and barely got the boat on the plane ( and that was a 30HP engine ).
Best thing I did was to trade in and get a new engine but certainly is not the cheapest way to do it. I have now replaced engine and trailer and could have bought a new package for much less.
So I would wait and get nearer to what is required.
