I have several old Evinrudes for which I am attempting to find the value so I can sell them for a 94-year-old man. The first does not run and is approximately 2-3 h.p. The attached tank is lacquered. It is an Evinrude Sportsman with a serial number of 4416-30373. The second is a 7.5 h.p. Fleetwin with the numbers 4434-21260. It is locked up. The third is a 5.5 h.p. Fisherman with the numbers 5514-03536, and has plenty of compression. The fourth is an 18 h.p. Fastwin, also with plenty of compression. It bears the serial numbers of 15020-12196. The last is a 28 h.p. Speeditwin, model number 282020, and serial number 02069. It also has a great deal of compression. I need to know the age and value of these motors. The 18 horse and 28 horse have never been in the water.
