Per-engine hour meters
Add one engine or several; each has its own hours and schedule.
Powerboat maintenance
Twin engines and a generator? Each keeps its own hours.
Boats run on hours, not miles. From a center console to a cruiser, add every engine and the onboard generator, and Wrench Wise™ tracks each one’s hour meter and marine service schedule (impellers, lower-unit oil, zincs, heat exchanger) alongside the hull, bilge and safety gear.

What Wrench Wise™ does for your boat
Onboard generator
The genset gets its own hour meter and a marine schedule: raw-water impeller, zincs, heat exchanger, sea strainer, oil and load testing.
Built for your hull
Bowrider, center console, pontoon, fishing, ski/wake, cuddy cabin, or simply powerboat for cruisers and power cats.
Inventory aboard
Spares, fluids and safety gear with where each is stowed, expiry dates on flares and extinguishers, and a To buy list when you run low.
Propellers on file
Record each prop’s make, model, serial number and hours.
Hull ID & documents
Store your HIN, registration and paperwork with the boat.
Winterization
Seasonal winterization and spring commissioning on the calendar.
Safety gear
Life jackets, flares and fire extinguishers checked on schedule.
Inventory aboard
Everything aboard, accounted for.
Start with the safety gear you carry, then add spares, fluids and tools with where each is stowed. Items running low go on the To buy list, and expiry dates come up before they pass.
