It depends on what shape it is in since it it is very hard to find replacement parts. If you would like to sell I might be interested, I collect old Mercs and have a few parts for the 200 model.
To determine the year of a Mercury Kiekhaefer 200 20hp outboard motor with the serial number 2439731, you can refer to the serial number chart provided by Mercury. Typically, for the 200 series, serial numbers in the range of 2430000 to 2450000 were produced around the mid-1960s. Thus, it is likely that this particular outboard motor is from the year 1966.
Mercurys of that age are a collectors motor but without knowing condition 25$ for a parts motor 100-200$ for a running example in good condition
Whats my revelation model 200 worth
