Larson 180 Sei
The Larson 180 Sei is a 18-foot boat, with model years from 1993 to 2007 in the listings we track. Across 19 listings we have observed (model years 1993–2007), the median asking price is $8,500, with most boats asking $5,000 to $10,000. The engine we see most often on this model is MerCruiser sterndrive (gas, 4.5L–6.2L).
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 19 sellers are asking, which is the number you are actually negotiating against.
18 priced listings across 8 states. Enough for a range, not enough to be precise about any single year.
Method: Asking prices from active listings, de-duplicated so a re-posted boat counts once (72 raw listings collapsed to 19 distinct boats). Quartiles, not averages, so one outlier cannot move the band. Rounded to $500.
Coverage: Model years 1993–2007, 8 states, 12 metro areas. New-boat listings excluded.

The BoatVerdict take
- BoatVerdict listing data
Supply is concentrated: our 19 listings came from only 8 states, led by MN. Expect a smaller buyer pool at resale, and budget for transport if the right boat is not local.
- Recall (USCG/CPSC)
13 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.

Asking prices from active listings we observed, not sold prices. No public source publishes US used-boat transaction prices; anyone showing you "sold" data for this market is estimating it. Years with fewer than 3 priced listings show the count only.
Method: Median and quartiles per model year, computed only where at least 3 priced listings exist for that year.

Engines we actually see on the 180 Sei
- MerCruiser sterndrive (gas, 4.5L–6.2L)
The most common inboard/outboard in US bowriders and cruisers. The engine itself (GM-based) is reliable; the maintenance burden is the drive and exhaust. Bellows, gimbal bearing, U-joints, and — in any saltwater service — exhaust manifolds and risers are the recurring costs.
Service reality: Bellows/gimbal every ~5 years; manifolds/risers every ~6–8 years (or 3–4 in salt) at $2.5–4K. Pull the drive on inspection — deferred drive service is the classic hidden cost.

What to inspect on a used Larson 180 Sei
- MerCruiser sterndrive (gas, 4.5L–6.2L): Bellows/gimbal every ~5 years; manifolds/risers every ~6–8 years (or 3–4 in salt) at $2.5–4K. Pull the drive on inspection — deferred drive service is the classic hidden cost. Seen on 3 of the 19 180 Sei listings we track.
- Get the hour meter reading and divide by the boat's age. Above 100 hours a year is heavy use for a MerCruiser sterndrive (gas, 4.5L–6.2L). Threshold from BoatVerdict's engine-family profile for MerCruiser sterndrive (gas, 4.5L–6.2L).
- On the older hulls, core moisture is the deal-breaker: sound the transom and the deck with a plastic mallet, and treat any soft or dull-sounding area as a survey-stopper rather than a bargaining chip. We observe listings back to 2001, so boats over 25 years old are actively traded in this model.
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 180 Sei listings. It is not a generic pre-purchase checklist, and it does not replace a surveyor.
What a 180 Sei costs to own
$1,500 – $4,000 per year
- 18 ft hull, the median observed length for this model
- Freshwater berth, based on where most listings we see are located (MN)
- Includes insurance, storage, routine service, fuel at moderate seasonal use, and a reserve for wear items
- Excludes loan payments, major engine replacement, and refit work
This is a modelled band, not observed spend. Real cost swings hard on where you keep the boat and how much you use it.
Method: The same ownership-cost model BoatVerdict's paid Deal Report uses: boat class and length set the base band, then saltwater berth and size adjust it.
