I think most of the motors described here are probably larger than what we sailors might use as kickers or dinghy
motors [for instance, the 41 motors stolen from the dealer in the lead paragraphs of the article were said to be worth $700,000, or about $17,000 each on average], but there are some interesting stats in the article:
"Florida, which ranks as the top state for boat
thieves, does keep track of engine
thefts. A CNBC analysis of records compiled by the Florida Fish
and Wildlife Conservation Division shows a total of 811 engine
thefts in 2016 compared with 643 in 2015. About half the stolen engines were Yamahas."
