I recently sold a 1985 9.9 Evinrude which belonged to a relative who passed away. It was in what I'd call near new condition. It was likely as close to a brand new motor as you could find these days. I had my doubts if it had actually ever seen the water on a boat.
I listed it here on FB and CL back in '21, it took till June of this year to sell. I had listed it for $800, the best or only offer I got in all that time was $500 cash.
I probably got 50 emails asking if it was a 2 or 4 stroke, another 100 or so asking if it would fit their boat, and dozens of emails telling me how 2 strokes should be junked because they ruin the environment. It sold to a guy who was here on work from out of state.
I have three 15hp Evinrude motors that I've owned since the 80's myself. All three are good running motors, but in 2000 I bought a new Mercury 9.9 four stroke, and my larger boat runs a 40hp. I kept one 9.9 and the three 15hp motors around as spares or just in case I didn't like the four stroke.
I had considered selling them but after all the headaches trying to sell that one motor I don't think its worth the hassle. If a minty clean motor in tip top shape will only bring $500, then my more used 15hp motors likely won't bring enough to bother carrying them out of the garage.
If I thought I could get any where close to $3,500 for them they'd be gone.
Its not just small motors that don't sell, a neighbor has been trying to sell his mid 80's 150hp in good running shape for $600 for three years and he's not had a single serious buyer either.
Boats and motors have always 'lost' value in the fall and winter here but this year I'm seeing way more dirt cheap deals for some nice looking boats, and they've gone for weeks unsold. I've for years watched the trend here for guys to dump their fishing boat and all their tackle in the fall to buy hunting gear, then in the spring dump their hunting gear to buy fishing tackle. They'd do it year after year and never 'keep' anything for the next season. A buddy of mine made a living buying and selling used hunting and fishing gear from guys who did this every year. Some guys claimed they did it so they had the latest and greatest gear every year, but most did it because they needed the money from what they sold to buy what they needed for the season at hand. Now it seems very few hunt or fish. I don't see nearly as many younger guys getting into hunting or fishing and the older guys have either gotten too old, or don't have the time, or got fed up with the ridiculous limits these days. (Going fishing and only being allowed to keep one fish just isn't worth all the registration, insurance, and fuel it takes to go get it).
