The 110 cubic inch OMC 120 would be my first choice for a CVX-16. My brother bought a '92 CSS-16 with a 120 Johnson new and it still runs perfect, never needing any repairs. Another brother has a 1986 Evinrude 140, also the 110 cubic inch, on his CVX-17 and it still runs perfect. They have been great motors for my family. $800 sounds like a great deal to me.
