Used amphibious equipment can be a sound purchase, but it needs assessing differently from a dry-land machine.
What to inspect
- Pontoon integrity. Internal corrosion and failed seals are the significant risks, and neither is visible externally. Pontoons that have taken water internally may look sound and be near the end of their life.
- Undercarriage wear. Submerged running wears components faster than hours alone suggest. Measure rather than estimate from the hour meter.
- Hydraulic condition. Water ingress into the hydraulic system is more common on amphibious machines and its effects are cumulative and expensive.
- Structural cracking. Check pontoon-to-upper mounting points and front pivot areas, which carry the highest cyclic loads.
Requesting an assessment
Send machine class, approximate hours, operating history — particularly whether it worked in salt or brackish water, which changes corrosion expectations substantially — and photographs of the undercarriage, pontoons and mounting points.
