2025 Harris Grand Mariner 250

The 2025 Harris Grand Mariner 250 is a 28-foot aluminum pontoon powered by a single 350-horsepower Mercury engine. Built with a contemporary design and finished in black powder coat, it features an SL/DH floorplan with Moonlit Shoreline full decking that combines style with practical maintenance.

The boat is equipped with a raised helm for visibility and control, along with a 3-tube black rubrail for stability. A four-step telescoping stainless steel ladder at the stern provides water access. Midship mooring eyes facilitate secure docking. The Mercury Verado power assist hydraulic system ensures responsive handling.

Entertainment and convenience features include a JL Zone Control audio system with eight JL speakers throughout, customizable C-Zone RGB cup and seat lighting for ambiance, and an interior light package. Standard equipment covers mooring eyes and the integrated full flooring.

The 8.5-foot beam provides ample space for entertaining, relaxation, or water activities. With minimal engine hours on a new model, the boat represents a fresh pontoon ready for extended use.
