You know the old adage – “An ounce of prevention is worth a pound of cure.” What is true for your personal well-being, is even truer for the health and longevity of your motor yacht. When it comes to any repair or problem, a skilled engineer or yacht mechanic will approach any problem, big or small, with these same five diagnostic signs. As a yacht owner, you should know them as well, and to ask your technicians about them. Knowing to ask the right questions, can ensure that repairs are done correctly and honestly.

1. Did you see anything obvious?

Ask about obvious signs of a problem, such as water in the bilge, hull damage, or the condition of the props.


2. Are there fuel issues?

Ask about the fuel pressure and quality. Find out if the filters or tank pickups are clogged. Ask if there are any signs of water in the fuel, or other contamination.

3. What about compression?

When trouble shooting engine issues, ask for the compression reading. Is it good? All the cylinders should be within 10 percent of each other.

4. Did you check the spark?

A problem in an outboard engine could be as simple as a poor spark.

5. What about fluids?

Ask about the condition of all lubricant and fluids such as, oils, gear lubes and transmission fluid. Did they find any signs of contamination, water, metal shavings or fuel dilution?
