Buyer questions
Eight questions buyers ask about the Harris Sunliner 250 SLDH Sport, answered from the boats listed on US Marine Connection right now.
Right now US Marine Connection shows 5 approved, priced Sunliner 250 SLDH Sport listings asking between $126,921 and $127,518, with a median asking price of $127,518. That is a tight spread, which makes sense since all five are the same 2027 Tower Sport build with a Mercury 300L FourStroke DTS. Keep in mind these are asking prices, not recorded sale prices, so the final number comes down to what you and the seller agree on.
Every one of the 5 listings currently on US Marine Connection is a 2027 model. There are no older model years showing for this boat at the moment, so you are looking at current-year inventory rather than a used market. All five are listed as the Sunliner 250 SLDH Tower Sport with a 300HP Mercury Marine 300L FourStroke DTS, measuring 25 ft 1 in, in either black or white.
None of the 5 listings states an engine hour figure, so there is no typical number to quote here. Since all five are 2027 boats listed at $126,921 to $127,518, hours are likely minimal, but that is not something the listings confirm. Ask the seller directly for an hour reading off the Mercury DTS display and request a photo of the gauge before you commit to anything.
The descriptions cover the basics only: 2027 model year, 25 ft 1 in length, Mercury 300L FourStroke DTS 300HP, and color. So confirm everything else in person. Ask for engine hours, service records and remaining factory warranty. On a tritoon, inspect the tubes for dents and scrapes, check welds and the underdeck, test the digital throttle and shift, and run the boat on the water. Verify the tower hardware and all seating and upholstery.
The listings are brief, so stick to what they actually state: each is a Sunliner 250 SLDH Tower Sport rigged with a 300HP Mercury Marine 300L FourStroke DTS, with a length of 25 ft 1 in. Colors offered are black on three boats and white on two. No other equipment, electronics or options are named in these descriptions, so ask the seller for a full option sheet and photos of the helm and seating layout.
That is the use the listings support. These are pontoon and tritoon boats at 25 ft 1 in, which is a layout built around seating, shade and easy boarding rather than offshore running. With a 300HP Mercury 300L FourStroke DTS and the Tower Sport setup, there is power on hand for towing a tube or skier. The descriptions do not mention fishing gear or offshore equipment, so plan on protected inland and coastal water.
All 5 Sunliner 250 SLDH Sport listings on US Marine Connection are in Houston, Texas, and all five include photos. There is no other city showing inventory for this model at the moment, so buyers elsewhere should plan a trip or arrange their own transport. If Houston is far, the sibling Harris models listed on the site cover more price points and may be worth a look.
On asking price, the Sunliner 230 SLDH sits below it: 9 listed, all 2027, all asking $109,299. The Grand Mariner 250 SLDH sits above: 8 listed from $159,583 to $192,657, median $171,074, in 2026 and 2027 years. The Sunliner 250 SLDH Sport falls between at $126,921 to $127,518. The listings do not describe layout or feature differences, so compare photos and option sheets directly with each seller.
