Looking at a albe 247. Do these boats have the same water ingestion problems as the carolina classic? For those in the know what is your opinion of these boats prior to 2000? What cruse can I expect with a 5.7 volvo? Is this enough engine?

The answer depends on how you want to look at it and is either a definate yes, a maybe or no. First, all boat engines can be subject to water ingestion just to varying degrees. No boat motor is immune to water ingestion.
Mercury issued a general service bulliten about the ingestion problem and it applies to all 4,6 and 8 cylinder Inboard and I/O engines.

The issue was most common in the Big Block GM based motor....particularly those that had a great deal of valve overlap(the 7.4 Volvo fits this category).I can't remember but I think the FI and Carb models had different cams and one is more succeptable than the other.
It is also more common in boats with thru-hull/waterline exhaust as oppose to thru/hub prop exhaust or thru transom mufflers (like a corsa? exhaust).
People are aware of the Carolina Classic ingestion issues because they built so many boats with the thru-hull/waterline exhaust and the big block 7.4 Volvo. Carolina Classic didn't really have any more problems with this than any other boat with the same configuration.The problem is more about the engine and exhaust configuration. Mac Privott now uses Crusader gas engines and Volvo & Yanmar diesels and they have had almost zero problems from the same hulls.
I don't know which exhaust configuration the Albemarle has but the smallblock is cetainly going to cut down on the problems and if it is a standard thru prop exhaust it will be even less.
I would ask the guys on the Albemarle Owners site about how well the 5.7 pushes that boat. Carolina Classic uses the 8.1 Crusader in the CC25 and 6.0 Crusader twins in the CC28. The HP/engine is about the same but the 8.1 has much more torque and they feel it is a better match. The 247 Albemarle is a good bit smaller and lighter than the CC25 so the 5.7/small block may be just fine.
