Hard to believe but they still make a lot of 4.3's for the marine industry. It is a hugely popular engine in brand new 2013 boats because of it's torque curve and suprisingly high torque numbers. I've got one in my pretty new boat and they are just great engines to say the least. They only just killed off the carbed version because of the EPA regulation. Simple and venerable is what sells in the marine industry...mostly. The only issue the marinized 4.3 has is it can develope run-on.
