115 FourStroke

Brief Summary

Mercury Marine’s line of second-generation 4-stroke outboard engines, all based on a larger 2.1-liter displacement block. Available in 75, 90 or 115 horsepower, these refined four-cylinder engines are cleaner burning, quieter and give better fuel economy with less maintenance than their predecessors, according to the company.

The naturally-aspirated fuel injected outboard is also said by the builder to be one of the lightest on the market, as much as 20 lbs. (9.07 kg) for the 115-hp version.
