Helm AI · Diagnostic engine
The diagnostic engine inside Helm AI.
BoatMD asks what a chief engineer would ask, narrows the cause, and hands you an actionable diagnostic report — then synchronizes the finding with parts, service, maintenance and your vessel history automatically.
How it starts
“What's wrong with your boat today?”
One question opens the session. From there BoatMD works like a diagnostic conversation: symptoms, follow-up questions, evidence, and a confidence-scored conclusion.

Sample diagnostic report
Likely cause: raw water impeller failure
Starboard engine over-temperature at cruise with reduced raw water discharge indicates degraded impeller vanes restricting flow through the heat exchanger.
Safety warning
Shut down and allow the engine to cool before opening the pump housing. Close the seacock before removing the cover.
- 1Close the raw water seacock and confirm zero flow.
- 2Remove the pump cover plate and inspect vanes for wear or missing pieces.
- 3Check the heat exchanger inlet for shed impeller debris.
- 4Install the new impeller kit with a fresh gasket and torque to spec.
- 5Reopen the seacock, run up, and verify discharge and temperature.
