Professional Pre-Purchase Boat Inspections You Can Rely On
Buying a boat without a proper inspection can lead to hidden issues and unexpected costs. This service gives you a clear and accurate picture of the vessel before you make a decision. We provide a complete marine mechanical inspection that Western Australian boat owners can rely on.
We are supported by authorised expertise from Volvo Penta and Yanmar. Each inspection focuses on engine condition, mechanical systems, and overall performance.
Whether you’re buying your first boat or upgrading, you’ll have the information you need to move forward with confidence.
Our Comprehensive Pre-Purchase Inspection Coverage
When you’re buying a boat, you need a clear understanding of its condition. Our inspection includes a full used boat engine check WA, covering all key components and systems. So you can move forward with confidence and avoid unexpected issues.
Engine & Mechanical Systems
You’ll get a full check of engine compression, engine mounts, and any signs of rust or corrosion. Key components such as belts, coolant systems, pulleys, pumps, the turbocharger, and exhaust are inspected to assess overall engine health and reliability.
Fuel, Oil & Hydraulic Systems
Oil conditions and levels are reviewed, along with hydraulic systems, to ensure smooth operation. The fuel system is also checked for leaks or faults that could affect performance or safety.
Electrical & Control Systems
Wiring, hoses, and hose clamps are inspected for wear, while batteries and charging systems are tested. Dash panels and fault codes are reviewed, and gear controls are checked to ensure proper response.
Cooling & Water Systems
Sea water leaks, sea cocks, pumps, and the sea water strainer are all inspected to ensure proper cooling and to prevent overheating.
Performance & Key Components
During the sea trial, speed and overall performance are assessed. Components such as propellers, rudders, stern thrusters, anodes, generator, and water tank are also checked to give you a complete view of the vessel.

Our 4-Steps Inspection Process
Our inspection process is designed to be clear, thorough, and easy to follow. Each step includes a structured marine engine diagnostic check to ensure accurate findings. We will arrive at your vessel for the delivery of your report and every step is carried out with attention to detail, so you know exactly what’s been checked and why it matters.
1.
Vessel Attendance & Initial Assessment
We will attend your vessel at the agreed location and begin with an initial overview. This allows us to assess the boat’s overall condition and prepare for a structured inspection of all key systems.
2.
Comprehensive Inspection & System Checks
Our detailed inspection is carried out across all major areas, including engine, mechanical, electrical, and supporting systems. Each component is carefully assessed to identify wear, faults, or potential risks that could impact performance or safety.
3.
On-Water Sea Trial & Performance Testing
The vessel is tested at sea to assess real operating conditions. Speed, handling, responsiveness, and overall performance are evaluated to give you a practical understanding of the boat’s performance beyond a static inspection.
4.
Report Preparation & Delivery
All of our findings are documented, including photos where required. A comprehensive report is then prepared with clear explanations and professional recommendations, and sent directly to you for review. Most of our inspections take 3–5 hours, depending on the size and complexity of the vessel.
Our Pricing Factors
Our pre-purchase inspection is offered at a set price, so you know exactly what to expect from the start. This includes a full inspection, sea trial, and a detailed report with no hidden costs.
Boat Size
The vessel’s size is considered in planning to ensure sufficient time and attention are given to all systems during the inspection.
Depth of Inspection
Every inspection is comprehensive, but certain vessels may require closer attention to specific systems depending on their condition and setup.
Location
The inspection location is considered to organise the visit efficiently and ensure the process runs smoothly.

Our Recent
Inspection Findings
Our inspections have helped buyers uncover issues that may not be visible during a standard viewing. We allow them to avoid costly mistakes and make informed decisions, such as:
- Hidden engine corrosion identified early, preventing significant repair costs after purchase
- Fuel system leaks are detected before handover, reducing safety risks and future breakdowns
- Cooling system faults were discovered that could have led to overheating during regular use
- Worn propellers and drive components are impacting speed and overall performance
- Early signs of engine wear are highlighted, giving buyers the confidence to renegotiate or reconsider
