Outboards: Merc Intros New 8 and 9.9s

June 13, 2024

Mercury Marine has introduced 8 and 9.9hp EFI FourStroke and 9.9hp EFI ProKicker™ outboard engines. These new outboards feature an advanced Mercury electronic fuel injection system designed to provide boaters, fishing enthusiasts and pro anglers with easy starts and efficient performance.

“In recent years, Mercury Marine has pushed the envelope at the top of the outboard performance range with our 350-400 and 600hp Verado engines, but at the same time, we have focused on developing the next generation of outboards in our lower portable range,” said John Buelow, Mercury Marine president. “Redesigning the 8 and 9.9hp family to include EFI delivers a host of consumer benefits such as faster starting and better fuel economy, which builds on our commitment to continuous improvement and delivering high quality products.”

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.

EFI technology takes the hassle out of starting in all weather conditions. While both the 8 and 9.9hp EFI models are offered with a choice of manual or electric start, the manual-start models do not require a cranking battery, adding to their convenience.

“When you pull the rope to start the motor manually, it automatically charges the entire electrical system to enable ignition,” said Jim Hergert, Mercury Marine senior category manager for 30 horsepower and below outboards.

The 9.9hp EFI is available with remote or tiller controls, manual or power trim. The 8hp EFI comes with an easy-to-use tiller control – Shifting, throttle, steering, manual tilt and the engine stop button all can be operated with just one hand.

Mercury’s engineering team balanced the powerhead on the new 8 and 9.9hp EFI outboards, and incorporated vibration and sound-dampening materials including soft-rubber mounts to deliver a smooth and quiet driving experience.

9.9hp EFI ProKicker

The Mercury 9.9hp EFI ProKicker offers all these benefits and doubles down with additional features designed with the pro angler in mind. The ProKicker’s high-thrust, four-blade propeller provides superior control, allowing anglers to dial in precise trolling speeds. The new EFI model also comes with Mercury’s heavy-duty Command Thrust gearcase for greater durability, as well as standard power tilt. 

“You just push the button and it effortlessly raises the motor when you’re ready to run on your standard main power,” Hergert said.

Whether you are chasing big fish or big adventures, the new Mercury 8 and 9.9hp and 9.9hp ProKicker outboards, equipped with next-gen EFI, ensure surefire starts and quiet, efficient performance for days of hassle-free fun on the water.
