I just purchased an 18ft 1984 Crestliner Nordic. The boat came with 2 engines, a 75 hp Chrysler (guessing late 70's vintage) and a 20 hp (guessing early 80's vintage). I have a more up to date engine that I will be replacing these with and wondered what these engines might be worth. When I bought the boat, I figured for sure the engines did not run. To my suprise, I put a battery to them, squeezed the primer ball, and they both fired immediately. Could someone help me with what I can expect to get for these two engines. Both have controls and the 20hp comes with a nice matching steel 'chrysler' gas can with gauge on it. Thanks in advance for the help
