Mercury 9.9HP 9.9E EFI Outboard

The Mercury 9.9HP 9.9E EFI is a compact, fuel-injected portable outboard in Mercury's 9.9 HP range, sized for small aluminum skiffs, inflatable soft-hull boats, jon boats, utility boats, and small sailboats rather than larger runabouts.

Who this size suits

A 9.9 HP motor sits at the popular, easy-to-handle end of the portable range: light enough for one person to mount or remove from a transom, yet with enough thrust for a small boat to move at a reasonable clip. EFI delivery is generally valued for simpler cold starts and steadier throttle response than a comparable carbureted motor, which matters most to owners who only run their boat occasionally.

What to check before buying

Before ordering any 9.9 HP outboard, confirm three things against the spec table for this specific listing: shaft length against your transom height, the control layout, and start type, since those details are not spelled out in this product description and vary across the 9.9 HP lineup. Also confirm your boat's recommended horsepower range and transom rating before mounting any motor this size.
