This boat is powered by twin MerCruiser 6.2L Axius stern drives with 300HP each, and it has 157 hours of lake use.

The SLX 310 has an expansive cockpit social area, an aft-facing lounger that converts to a sunpad, and a standard wetbar make relaxation and onboard entertaining a given. Underway, the delight of good company merges with the thrill of precision performance, as the SLX's available twin MerCruiser® engines and innovative Quiet Ride™ hull featuring Tuned Transom® combine forces beautifully.
