The 400 LXF Li-Ion is an alternative version to the current 400 LXF, complete with a lithium ion battery management system (no generator necessary). These batteries are charged by the Mercury engines as well.While it's loaded with standard features (like the standard SeaKeeper Gyro Stabilizer), the available options are numerous. Options like the patented electronically-actuated articulating rocket launchers and the convertible leaning post that includes a Kenyon grill, sink and cutting board further distance this model from anything else in its class. The standard hydraulic port side beach platform with synthetic teak further adds to the model's characteristics, making it not just an incredible boat. It's an incredible experience.
