Editorial & Inventory Data Policy

Our publishing rule is simple: separate what a manufacturer says about a model family from what is known about a specific used unit.

Content updated: Editorial and inventory data policy

Usage-time reference and verification

A usage-time figure, when shown, is a planning reference rather than a certified reading. Before purchase, reconcile it with the current meter, serial number and service history for the exact unit. Where identity or values conflict, the page withholds a single figure and discloses the review issue. A missing year or installed engine remains unconfirmed.

  • Treat hours as a reference
  • Verify the exact unit
  • Confirm before purchase

Evidence hierarchy and manufacturer sources

For unit identity we prioritize a readable plate tied to the stock ID and current inspection evidence. For model-family context we use the original manufacturer's current or archived page, brochure, parts record or instruction record. A family reference never overwrites a unit plate, and specifications from a similar model or marketplace listing are not inserted as facts.

  • Unit evidence first
  • Official family source second
  • No silent substitution from a nearby model

Weight, dimensions and conflict disclosure

Weight is labelled as a unit-nameplate value or a manufacturer/model reference and remains configuration dependent. Freight planning uses measured dimensions in the intended dismantled or packed state. Duplicate imagery, model discrepancies and known data conflicts are disclosed on the affected listing.

Availability and condition

A published listing is not a live reservation guarantee. Availability, operating condition, configuration, service history and included accessories must be reconfirmed with Leo.

Buyer-guide sources

Buyer guides favor primary manufacturer, standards, customs, port and official technical sources where available. Sources are listed on each article and commercial claims are kept separate from technical facts.

Updates and corrections

Material content changes carry an updated date. If a listing or guide appears inaccurate, email Leo with the page URL and the fact that should be checked.
