I do not have any good theory why used outboard motors which are advertised on-line tend to be Yamaha brand. And I am not really willng to stipulate that your observation is correct. If we proceed on the basis that there are more used Yamaha motors for sale on-line, could you clarify what point you are asking about? Is it the on-line advertisements in particular you want to investigate? Or do you think that of all used motors being offered for sale everywhere, Yamaha is the dominant brand?In general I would expect the on-line advertisements to mirror the total marketplace. I do not see a particular reason for one brand to be favored over another, although it could be that just one or two very active sellers of Yamaha engines using on-line advertising could create the impression of greater market share for Yamaha.
In the overall used outboard market, I expect that sales will mirror the new engine market share. Yamaha has a substantial market share, probably on the order of 35-percent. In some areas, particularly some saltwater markets, they are very strong and have an even greater market share.
One could also make the inference that perhaps Yamaha motors last longer and thus are more likely to be sold as used motors. Competitor motors of a similar age are worn out and abandoned. Perhaps, but there is no real data presented to support that.
Of course, one could also make the inference that Yamaha motors are more troublesome than other brands, so their owners want to sell them more often and replace them. Again, no data available.
I don't think you can make any kind of valid analysis without better numbers.
As for having a reticence to buy a used Yamaha outboard because you see large numbers of them for sale, I don't think this is necessarily a good conclusion. The general reputation of Yamaha is very good. They did have some recent models which had an unusually high rate of failure (for Yamaha, which usually has--according to conventional wisdom--a very low defect rate in their new product).
What specific model are you looking for?
