Mavimare GF 150 BRT Hydraulic Steering for 150 HP Outboards
The Mavimare GF 150 BRT is a heavy-duty hydraulic steering system engineered for outboard motors with a maximum rating of 150 HP. This mechanical assembly utilizes a high-pressure pump and cylinder constructed from marine-grade aluminum and 316 stainless steel. All included fasteners are A4 grade stainless steel to ensure resistance against corrosion in saltwater environments. The system is designed for engines with a 30 inch shaft length and provides precise directional control for vessels equipped with mid-to-high range outboard power. This unit is compatible with standard BIA mounting patterns and is intended for professional installation on recreational or commercial watercraft. Proper hydraulic fluid levels must be maintained for optimal operation.
