FREE, PRACTICAL MARINE GUIDANCE
Diagnose smarter. Spend only when you need to.
BoatMechanic gives boat owners a free, structured way to work through common engine symptoms at home. The goal is simple: help you understand what to check first, avoid unnecessary parts and labour costs, and know when it’s time to call a professional.
Free to use, designed to make everyday fault-finding clearer.
How the website works
Each guided checklist breaks a symptom into clear, sensible checks — without jargon or guesswork.
01
Choose the main symptom
Start with what your engine is doing — for example, overheating, poor idle, charging faults, or gearbox problems.
02
Follow practical checks
Answer each question in order. When a check needs attention, the site explains what it means and what to inspect next.
03
Use the result wisely
Save the guidance as a practical record, tackle straightforward issues yourself, or take clearer information to a marine technician.
Ready to narrow down the fault?
Start with the symptom you can see or hear, then let the checklist guide the next sensible check.
A sensible first step:
BoatMechanic offers general diagnostic guidance, not a replacement for safe working practices or professional repair when a fault is serious, unclear, or safety-critical.
