Buyer questions
Eight questions buyers ask about the Harris Grand Mariner 250 SLDH, answered from the boats listed on US Marine Connection right now.
On US Marine Connection right now there are 8 priced Grand Mariner 250 SLDH listings, asking between $182,553 and $192,657, with a median asking price of $184,392. Keep in mind those are asking prices, not recorded sale prices. It's also worth noting that every one of these listings is described as a new unit in the 2026-2027 model years, so there is no true used pricing in the current group to compare against.
The current listings cover model years 2026 and 2027 only. All 8 are described as new units rather than pre-owned, so there are no older model years in the group at the moment. If you are shopping for an earlier boat, the site simply doesn't show one for this model today. Each of the 8 listings does include photos, so you can see the specific boats before reaching out.
No listing for this model on US Marine Connection states an hour figure, so there is no typical number we can give you honestly. That is consistent with what the descriptions do show: all 8 boats are listed as new units in the 2026-2027 model years at a Houston, TX location. If hours matter to you, ask the seller directly to confirm what is on the engine before you commit.
Since these listings are 2026-2027 units with no stated hours, start by confirming actual hours, warranty status and whether the boat has been rigged or water tested. The descriptions name a Mercury Marine 350L Verado outboard, so verify the engine matches the listing, check the transom and mounting hardware, and inspect the pontoon logs for dents or scrapes from handling. Also confirm the 25 ft LOA fits your slip, lift and trailer setup.
The dealer descriptions are short on detail. What they consistently list is a 25 ft LOA, a Mercury Marine 350L Verado outboard (a couple specified in white), and powered propulsion, with each boat carrying its own stock number. Anything beyond that, such as seating layout, canvas, audio or electronics, is not stated in the listings, so ask the seller for a full option sheet rather than assuming a package is included.
It fits that use well based on what the listings show: a 25 ft pontoon and tritoon platform with a Mercury 350L Verado, which is the kind of roomy, stable deck boat people use for cruising and hanging out with a group. The descriptions don't detail seating, fishing stations or rough water capability, so don't count on specifics like those until the seller confirms the layout on the particular hull.
All 8 of the current Grand Mariner 250 SLDH listings on US Marine Connection are in Houston, TX. There are no other cities showing this model right now, so buyers outside Texas would be looking at travel or shipping arrangements. Each listing includes photos and a stock number, which makes it easier to reference a specific boat when you contact the seller about availability.
Mostly it is a price and model-year gap. The Grand Mariner 250 SLDH shows 8 listings asking $182,553 to $192,657 (median $184,392) in 2026-2027. The Cruiser 230 SLDH has 4 listings from $55,384 to $61,047 (median $58,049), model years 2023-2026. The Cruiser 190 SL shows 3 listings, $44,025 to $48,297, median $46,143, all 2027. The listings don't give enough spec detail to compare layouts or performance.
