And just checked the price £1000! Well done indeed - that's an easy £1800 - £2000 value there if split in my experience. Just goes to show why time and time again over the years and as per the sticky Fenlander, myself and many others advise first time SIBbers to look out for outfits exactly like that. Buy it, try it and if not for you split and sell on for a profit. After a few years you effectively make money and end up with an outfit for free.
Do it that way or the wrong way - ie don't do any research, rush into picking up the wrong boat, buy the wrong engine, sell at a loss, repeat, etc.
Always, always just look for a well matched big name outfit with extras included in the 3.2 to 3.8m range (airfloor will suit most far more than solid floor) with a 9.8 to 15hp 2 stroke and at the £1000 to £1800 price range. As an all round SIB set up this will be perfect for the vast majority of users.
