Harris 250 Grand Mariner

BoatVerdict market snapshot

These are asking prices. No free or public source publishes US used-boat transaction prices, so nobody — us included — can honestly show you what these boats sold for. What we can show you is what 20 sellers are asking, which is the number you are actually negotiating against.

The BoatVerdict take

• Recall (USCG/CPSC)

  5 federal recall campaigns on file touch this builder. Check the specific hull against the recall list below before you put money down; remedies are free but only if the work was actually done.

Each point is tagged with the evidence behind it. Nothing here is a claim we cannot trace back to a counted listing, a federal record, or a named analyst judgement.

Engines we actually see on the 250 Grand Mariner

• Mercury Verado / V8 FourStroke (250–400) 2 listings · 10% of our sample · median 350 hp

  Modern Mercury V8/V10 FourStroke and supercharged Verado are strong, smooth, and well-supported, a clear step up from the OptiMax era. Slightly behind Yamaha on resale trust but closing fast, and often better integrated (joystick, digital throttle).

  Service reality: 100-hour service; supercharged Verado adds the supercharger oil interval. Check for corroded battery cables and the SmartCraft harness on saltwater boats.

Harris 250 Grand Mariner specifications

Rows marked "our listing data" are measured from listings, not published by the builder, and will differ from a brochure. Rows without a source we can name are not shown at all.

What to inspect on a used Harris 250 Grand Mariner

1. Mercury Verado / V8 FourStroke (250–400): 100-hour service; supercharged Verado adds the supercharger oil interval. Check for corroded battery cables and the SmartCraft harness on saltwater boats. Seen on 2 of the 20 250 Grand Mariner listings we track (typically 350 hp on this model).
2. Get the hour meter reading and divide by the boat's age. Above 150 hours a year is heavy use for a Mercury Verado / V8 FourStroke (250–400). Threshold from BoatVerdict's engine-family profile for Mercury Verado / V8 FourStroke (250–400).
3. Assume saltwater service unless the seller can prove otherwise: pull the engine cowling and look at the powerhead, check trim-cylinder rams for pitting, and open the battery and fuse boxes for green corrosion. 63% of the listings we observed for this model are in coastal states.

This list is specific to this model: analyst items for the hull, plus items driven by the engines and the regions we actually observe on 250 Grand Mariner listings. It is not a generic pre-purchase checklist, and it does not replace a surveyor.
