Evinrude E90SNL Outboard Motor

This used Evinrude E90SNL is a pontoon-series Evinrude, a three-cylinder engine tuned to the same gear ratio and throttle mapping used across the brand's other pontoon-rated outboards. Why it suits a pontoon The gearing and mapping here chase easier low-speed maneuvering and a smoother, quieter ride with a loaded pontoon than a standard-mount outboard delivers on the same hull, which matters most at docking speed with passengers aboard and gear loaded. What's on the spec sheet Total displacement is 79 cubic inches, the primary ratio comes in at 2.36:1, and this motor tops out in a 5,000-to-5,500-rpm window. This unit runs mechanical controls, starts electric, and weighs 320 lbs on its 20-inch shaft. Rigging recap Power trim and tilt on this unit are handled through a Trac-1 system rather than any manual lever, and the 20-inch shaft figure is what to check against your pontoon's existing transom bracket before ordering. Pontoon tuning versus a standard mount Because the gear ratio and throttle mapping on this engine are built around a pontoon's flatter hull and passenger load, it generally is not the right swap onto a deep-vee runabout or a bass boat looking for top-end speed, even though the underlying three-cylinder block is shared with Evinrude's standard-mount 90-hp motors. What brand is this engine? Evinrude. Are the controls mechanical? Yes.
