Harris Boats Expands Premium Lineup with Twin-Engine Summit Series
Harris Boats is expanding its premium pontoon lineup with the introduction of the Twin-Engine Summit Series, now available on the Crowne and Grand Mariner 260 models with twin Mercury Marine outboards.
Harris Boats has announced an all-new premium Summit Series for 2027.
The new Summit Series is built around Harris Boats’ RPM Technology and features twin-engine propulsion, Mercury Marine Joystick Piloting (JPO), and a Simrad NSX ULTRAWIDE display as standard equipment.
“We’re excited to introduce the new twin-engine offering with the launch of the Summit Series, further rounding out our portfolio in the ultra-premium pontoon market,” said Alex Meize, Director of Harris Boats Product and Strategy.
“Built on our RPM Technology, which delivers exceptional Ride, Performance, and Maneuverability, the Summit Series combines confident handling with premium comfort and luxury to create an unmatched on-water experience. There’s no better time to celebrate this exciting addition to our lineup than during our 70th anniversary year.”

Harris introduced the new template Crowne 250 in 2024 as a full keel-up redesign and the largest overhaul of the model since its introduction in 2004. The redesigned pontoon features a full fiberglass body, digital switching, and the Zero G Lounger, along with Harris’ unique RPM Technology.
In 2024, Harris also announced its first all-electric pontoon, the Cruiser e-210, powered by a Mercury Avator 35e electric outboard. The 23'2" pontoon used the Cruiser SLDH layout and featured a 2,300 Wh lithium-ion battery developed by Mastervolt, with an Avator 35e outboard producing 3,700 watts of continuous power.
Earlier in 2026, Harris also introduced a redesigned Sunliner lineup, covering 210, 230 and 250 models, along with the new Sunliner Sport. The redesign included an all-new rear sun-lounger entertainment layout, an elevated helm with a redesigned console, flush stainless-steel switches and wireless charging.
