2026 Harris Grand Mariner 250

The Harris Grand Mariner 250 is a 25-foot aluminum pontoon powered by twin Mercury 350 hp engines, built to handle leisure cruising and water sports. The redesigned profile features clean lines and a contemporary silhouette, while the layout maximizes usable space with optimized storage and seating throughout the deck.

The interior centers on comfort and control. Soft-touch vinyl furnishings in caviar black pair with slate gray woven teak flooring. The raised helm features an ultra-luxury high-back captain's seat with slide adjustment, a power-assisted steering wheel upgrade, and C-Zone digital helm technology. A fully electric tower with black bimini top and ion lighting provides shade and style, while a refrigerator and changing room with curtain add onboard convenience.

Entertainment and water sports amenities are well-equipped. The system includes a JL Platinum speaker package and an entertainment center. A stainless steel three-tube ski tow bar extends the boat's capability for towing. Interior and exterior lighting packages and a power-lift tower with black bimini complete the specification sheet. Adjustable seating, additional deck plate removal with lifting systems, and a rubrail kit in black round out the features.
