A replacement engine is £7-10k all in for a 20 or 30hp. A little less for a smaller boat with a 10-16hp. Replacement is common because marine engines die of neglect mainly rather than wearing out and 30-50 year old boats that are near the bottom of the pile get neglected as owners lose interest or their circumstances change. Most of the older engines - Volvos, Yanmars Bukhs mainly were seawater cooled with poor electrics living rarely used in damp surroundings. Newer engines are freshwater cooled and most GRP boats can be made watertight so engines have an easy life, particularly if used regularly and hard.Replacement engine: how much would be a fair estimate?
I'm amazed at how many boats have replacement engines.
Normally Beta, and normally already under-offer or sold!
I agree with others - don't get too fussed about the specific designs, condition gear and you are far more important for success. Bilge keels offer little advantage as you will find almost all areas have deep water anchorages or harbours. However if part of your plan is to explore the many tidal rivers and estuaries then of course the ability to dry out or sail in shallower water is an advantage.
Consider a larger boat than 8m because with that budget you could get a sound boat in the 9-10m range such as a Sadler 32, Westerly Fulmar, Moody 31 and many others that would be more comfortable, reduce passage times by 15-20%, allow you to sail in a wider range of conditions and motor better. No more difficult to sail - indeed probably easier. If sound when you start the running costs will be little different on a trip like that, although of course long term running costs, particularly berthing will be higher.
Suggest you have a look here forums.ybw.com/members/concerto.147919/#about Roger did his circumnavigation in a Fulmar and shared a lot of useful information along the way.
If you fancy something older but with a bit more class, have a look at a Golden Hind 31 like mine which is close to being perfect for the job. Good ones sell comfortably within your budget.
