Your boat cannot go anywhere without a good outboard motor, and a boat that sits still is not much fun when you want to go fishing or just enjoy a sunny day on the water. You also want to make sure you have exactly the right horsepower, and for smaller or inflatable boats, a 15 horsepower outboard motor should do the trick. The 15 horsepower model is common, and many reputable brands manufacture it, each with its own specifications and features. One of the most popular ones on the market is the 15 horsepower Mercury outboard motor line. The Mercury FourStroke outboard motor is famous for being green, as it surpasses the state of California's strict Air Resources Board rating. It is quiet and fuel-efficient, with a manual starter and a 6.6-gallon fuel capacity. Yamaha is another popular brand, and the 15 horsepower Yamaha outboard motor has a 4-stroke engine, 20-inch shaft link, three-blade aluminum standard propeller, and forward, neutral, and reverse shift. Whatever 15 HP outboard motor you decide on for your boat, you can find it among the vast inventory on eBay.Shop the large inventory of motors, parts, accessories, and other complete outboard engines!
