I am thinking of buying a Boomeroo 25 which is an Aussie built Catalina 25. It is being offered at just above half of the going price for these boats. the boat is very clean inside and also looks good on the outside - it's afloat at the moment. It has a new 7HP Bukh diesel with 12 hours running. The problem is that the owner hit something with the prop - he says it spluttered and stopped and will not start again. He says Bukh have told him he might have bent a valve but I don't see how that could have happened. He says it needs a new prop., new standing rigging and a new main.
Should I get a survey with it out of the water? What should I look for - bent prop shaft etc?
If there is no visible damage to the hull, should I take the risk?
