Marine ElectricalDiagnostics & Troubleshooting3MediumOwner$ implied
Jet ski engine struggles to turn over when hot after running, but starts fine when cold, likely due to heat-soak issue.
Existing diagnostic tools do not address intermittent heat-related starting issues in marine engines, requiring manual trial-and-error part replacement.

Workarounds Described
- waits 30-45 minutes for engine to cool before restarting
Implied Software Gaps
- Diagnostic tool that correlates engine temperature with starting difficulty and isolates the failing component.
App Concept
MarineStart Diagnostics
A mobile app and OBD-like diagnostic tool that monitors engine temperature, voltage, and starter current in real-time to pinpoint heat-soak related starting failures. It logs data and suggests likely culprits (e.g., starter motor, wiring, sensors) based on heat cycle patterns.
Key Features
- Real-time engine temperature and voltage logging
- Heat-soak start failure analysis algorithm
- Step-by-step troubleshooting guide
- Data export for mechanics
Target Users: Personal watercraft owners and marine technicians in the recreational boating industry, especially those with high-performance engines.
Revenue Model: $12.99/mo subscription for app features; $99 one-time for hardware adapter plus first year subscription.
