Mercury launches 8.0hp, 9.9hp EFI outboard engines
Electronic fuel injection comes to Mercury’s tender-friendly portable outboard engine rangeMercury has ditched the need to carry a battery for two of its most popular tender outboard engines, adding electronic fuel injection to its 8.0hp and 9.9hp models in a big step forward for the brand.
Mercury also has made maintenance of both engines even easier, with camshaft and valve clearances that will not require regular servicing.
The addition of EFI also brings another bonus, with fuel use cut by up to 27 percent compared with the carburettor outboard engines that the new 8.0hp and 9.9hp models replace.

“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,” Mercury said.
“...[T]hese outboards produce more top-end horsepower than prior-generation carbureted engines, at a substantial weight savings compared to most EFI outboards in their class.”
Both the 8.0hp and 9.9hp outboard engines – the larger one is marketed in the US as a "Pro Kicker" motor for trolling at a lower speed than the boat's main outboard engine is capable of moving at – will come in the choice of tiller steer or forward control, and with either manual or power trim.
The 8.0hp EFI outboard engine uses a tiller control that includes shifting, throttle, steering and manual tilt, with the engine stop button also within easy reach of the hand using the tiller.
Work has also gone into balancing the powerhead on both engines, which feature new vibration and sound-dampening materials such as soft-rubber mounts to make them smoother and quieter.
Electronic fuel injection works by precisely controlling the amount of fuel entering the engine’s cylinder to suit its running conditions.
On manual-start models, the EFI system kicks in as soon as the starter cord is pulled, removing the need to have a separate battery to power it.
