The Vodomjerka is an unmanned Gear that can glide across the water. It slides around a lot including horrizontally. It has a few melee attacks including spinning attacks that move quite a long distance towards you but the most common attack is the flamethrower. Simply Ninja Run sideways to avoid this attack. Most of the time, the easiest way to deal with these enemies is to just get right in under one of their arms. As long as you can stay close to them, they'll keep trying to hit you with their flamethrower and they'll just keep missing.
