2026 Mercury Marine® FourStroke 9.9hp EFI

Lightweight and efficient Thanks to EFI technology and other enhancements, these engines deliver up to 27% better fuel economy than earlier carbureted models in the same horsepower range. They are light enough to be portable, making them ideal for powering spontaneous adventures on the water in trailerable fishing boats and other small craft, including inflatable tenders. Pound for pound, these outboards produce more top-end horsepower than prior-generation carbureted engines, at a substantial weight savings compared to most EFI outboards in their class. Easy to maintain EFI technology also makes these engines easy to maintain and there is no oil filter to change. In addition, their maintenance-free camshaft requires no regular service and no valve lash adjustments for the life of the engine. The new engines also come with a quick-connect fresh-water flush attachment that connects to a regular garden hose.
