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.
