The Complete Handbook of Watercraft Fuel Meters
Selection, Installation, Maintenance, and Repair for Marine Professionals and Serious Boat Owners

non-fiction
How to pick, fit, and keep accurate fuel meters on boats — for pros and serious owners.
About this book
Fuel flow data on a watercraft can mean the difference between making a passage on reserve or bobbing dead in the water. But the meters that provide that data are frequently misapplied, badly installed, or left to fail quietly. This handbook walks through the three main metering technologies — turbine, oval-gear, and ultrasonic — and explains exactly what each can and cannot do on a diesel or gasoline engine, a planing hull or a displacement hull, a common-rail or a mechanical injection system.
The book doesn't stop at selection. It covers the physical realities of installing a meter: orientation, straight pipe runs, grounding, and dealing with the vibrations and voltage spikes found in real engine rooms. You'll get a structured approach to troubleshooting when a meter drifts, reads zero, or becomes erratic, plus a maintenance schedule that fits a normal haul-out cycle.
For professionals, there's also a dedicated chapter on the business of fuel meters — supplying, installing, servicing, and even manufacturing them. Whether you're a one-person mobile mechanic or a yard with a full service department, the economics, common pitfalls, and customer expectations are laid out clearly.
Reader Reviews
Ryan Green
★★★★★It's got solid, practical info and I appreciate that it's not trying to sell me anything. The installation chapter alone is worth the price if you're putting a meter on a diesel. That said, I wish it spent more time on the older analog gauge setups that a lot of us are still running. It's clearly written for someone who's starting from scratch or doing modern digital installs. Good reference, but a bit narrow in the troubleshooting section.

★★★★★I've been a marine mechanic for about twelve years and I picked this up mostly to see if there was anything new. The comparison between turbine and oval-gear meters was clearer than what I've seen in most service bulletins. The chapter on business opportunities actually got me thinking about adding meter calibration as a service. Only knock is that the brand comparisons are already a bit dated, but that's the nature of the industry. I'll keep it in the shop.

★★★★★Bought this when I was upgrading the fuel monitoring on my trawler. I had a cheap turbine unit that never read consistently, and I didn't understand why until I read the section on pulsation and minimum flow rates. The troubleshooting flowchart is genuinely useful — it helped me figure out my ground loop problem in about an hour. Four stars because some sections get pretty technical and I needed to re-read them a couple times. But the information is all there.

★★★★★Finally, a fuel meter book that doesn't assume I'm an electrical engineer. I installed an oval-gear meter on my Cummins 6BT last month following the chapter on installation, and it's been dead accurate across the whole RPM range — the calibration procedure is the clearest I've ever seen written down. The example of the trawler that burned through its reserve because of a misreading sensor was a wake-up call. This is the reference I wish I had five years ago.

★★★★★Decent reference for a niche topic. The glossary alone is helpful when you're trying to interpret spec sheets from three different manufacturers. I wanted more depth on the ultrasonic style — the author clearly favors the mechanical meters — but the discussion on fuel quality and how it affects readings was really informative. If you're a serious owner or a working tech, it's a good addition to the shelf.
