Howdy I'm looking at a 1974 Viking 40 Convertablehttp://www.boattrader.com/listing/1974-Viking-Boats-40-Convertible-(md)-98618335 ... I'm looking for some info... It has 500 hours since the last major overhaul, awlgripped (what's that!?) in 2010, and has the original engines. my question: for 25 grand, it looks like a steal. with the original motors though, i'd be worried. is it tough enough and still well enough to take a canyon trip, about 90 - 100 miles both ways? other than that it looks really nice thanks!
