Boat Service Tracker & Log

Boat Service Tracker is the boat maintenance log and service tracker for your boat, built around the number that matters most: engine hours. Log oil changes, impellers, zincs, filters and haul-outs, and see at a glance what's due — by hours or by date, whichever comes first.

KNOW WHAT'S DUE
Tell it about your boat and its engines and the schedule builds itself: outboards (4- and 2-stroke), sterndrives, gas and diesel inboards, jet drives, generators and electric motors, plus the hull, systems, safety gear, sail rig and trailer. Every item comes due every so many hours or months — the oil change at 100 hours or once a year, the impeller every couple of seasons, flares when they expire. Read the hour meter, and the Due list sorts itself: overdue, due soon, coming up.

A LOGBOOK BUILT AROUND ENGINE HOURS
Twin engines serviced together are one entry, each at its own hours. Record what was done, parts and part numbers, the shop or "did it myself", what it cost, and notes for next time. Search it all later ("when did I last do the impeller?"), or share a service with your mechanic. Your engines' recent pace estimates when the next service by hours will land.

FUEL LOG AND BURN RATE
Log every fill-up: how much, what you paid and where. See what the season's fuel costs and your average price per gallon — and fill to the top with the hour meter read at the pump, and it works out what your boat burns per engine hour.

PARTS & SPECS FOR EVERY ENGINE
The oil and how much it takes, filter, impeller and spark plug part numbers, gear lube, anodes and the prop, on one card per engine: walk into the parts counter with the right numbers.

SEASONAL CHECKLISTS
Step-by-step winterizing, spring launch, haul-out, pre-departure and after-a-trip lists, built for your boat and every engine on it. Tick items as you go, add your own, and finishing a checklist logs the services it covered — winterizing resets the oil-change clock too.

A TO-DO LIST FOR EVERYTHING ELSE
The cracked deck drain, the flickering nav light, new dock lines: jobs that aren't on a schedule go on the boat's to-do list, and a finished one becomes a logged service in one tap.

EVERY RECEIPT AND PHOTO STAYS WITH THE BOAT
Photograph the receipt, the impeller you pulled, the zincs before and after, or attach the shop's PDF invoice. Keep the registration, insurance and survey with the boat.

A SERVICE RECORD THAT ADDS VALUE AT RESALE
Skipped service is how engines fail expensively, and a documented history is what buyers and surveyors ask for. Export a clean PDF service record — engines and hours, parts and specs, the status of every maintenance item and the full history with photos — or the service and fuel logs as spreadsheets. Repowered? The old engine stays on the record with its history.

REMINDERS THAT DON'T NAG
A heads-up a week before a service comes due and again on the day, plus a gentle nudge to read the hour meter. One reminder a day at most, and only if you turn them on.

FOR EVERY KIND OF BOAT
Powerboats and center consoles, sailboats, pontoons, fishing and bass boats, cabin cruisers and yachts, personal watercraft — on a trailer, at the dock or on a mooring, with one engine or three.

YOURS, ON YOUR PHONE
No account, no sign-up, works offline. Back up everything — photos included — to one file, and restore it on your next phone, Android or iPhone.

The free version keeps one boat with its full schedule, logbook, fuel log, checklists, reminders, spreadsheet export, backups and up to 25 photos and receipts. Pro adds unlimited boats, unlimited photos and receipts, the PDF service record and spending by category, and removes ads.

Service intervals are typical figures for each engine type; your engine's manual has the final word.
