I'M THINKING ABOUT BUYING A 2520 DVSC I/O WITH A 350CI VOLVO DUOPROP. THE HULL IS A 95 BUT ENGINE IS NEW IN 06. COULD ANYONE OFFER THEIR ADVICE ON WHAT TO LOOK FOR IN ANY COMMON CONCERNS THAT MAY INFLUENCE MY PURCHASE? I PLAN ON FISHING BOSTON HARBOR AND MASS BAY WITH OCCASIONAL OFFSHORE TRIPS ALONG WITH HAULING LOTS OF LOBSTER POTS. ANY COMMENTS ON DV VERSUS MV AND THE RELIABILITY OF THE VOLVO OUTDRIVE WOULD BE APPRECIATED. THANKS IN ADVANCE.
