Like having an engineer in your pocket
You don't need to know your way round an engine to use Nuts & Boats. It asks you what to look at, explains what you're seeing, and tells you what to do about it. Then it remembers, so next season you're not starting from scratch.

One question at a time
A guided check for outboards and sterndrives, and for your trailer too. Tap the answer that matches what you see, and add a photo if you like.

A report in plain English
Every finding explained: what it means, how serious it is, and what to do next. Laying up? You get your winter job list. Buying? You get the questions to ask the seller.

Your boat's history, kept properly
Log every service and repair, whether you did it yourself or a dealer did. Snap the invoice. See what's due, by hours or by date, for every engine.
Anyone with a boat, or about to buy one
Owners
Laying up for winter or getting ready to launch. Find the jobs before the first trip finds them for you, and keep a record that makes your boat easier to sell.
Buyers
Looking at a used boat? Walk round the engine with the app before you hand over any money. Know what's worth asking about, and what could cost you later.
Sellers
Show buyers an honest picture of the engine and a service history they can trust. A boat with its paperwork in order sells faster.

Made for real boats, not showroom ones
Nuts & Boats comes from years of seeing the same problems turn up on the slipway. The ones that could have been caught with a five-minute look and a bit of know-how.
- A two-minute trip checklist. Weather, fuel, kill cord, lifejackets. Make it your own: add the kids' medicine or the chart updates.
- A history you can trust. Entries added long after the work, or hours that go backwards, get flagged, so a full history actually means something.
- Your details stay yours. Black out names and addresses on invoice photos before anyone else sees them.
- Every engine on board. Twin engines, part numbers, and your engineer's and insurer's numbers, all in one place.
