What is the difference between the KAD-41, AD41, KAD-42/43/44 diesel engines? Then there's the D4. I'm looking at a 27' Sea Sport that has the AD 41P-A engine, with Volvo Penta DP-E duoprop. New in 2004 with 900 hours on it.
I understand that preventive maintenance is all important, but given that it was taken care of, is this a good setup? Are anyone of those engines better than the other? Anything to look at in general with these engines? From searching these forums, I've read that the KAD42 was one to stay away from? What would the advantages/disadvantages be of this engine vs a 5.7L Mericursier?
There are a number of Sea Sports with diesel engines for sale in SE AK. Is there any particular reason for this? Are they packing it in? Going to outboards? Aluminum? Or just the normal ebb and flow of boat ownership? Thanks for your responses.
