The 40-horsepower outboard is one of the most sought-after in the market. It is the engine of choice aboard charter boats-and generally preferred by those without a boat license. In fact, the maximum power that can be driven without having a boat license is set by law at 40.8 hp, as long as the displacement is less than 1000 cc for four-stroke outboard engines and less than 750 for two-stroke engines. For these reasons, all manufacturers-both those who make heat engines and those who make electric motors-have positioned themselves in this market segment, offering a model of 40 horsepower or equivalent. Here is a comparison of the top 10 40-hp outboards on the market.
Comparison – 10 40 hp electric and thermal outboards
