The Complete Handbook of Watercraft Fuel Pumps & Parts

Finally, a reference that treats fuel pumps like the engineering components they are, not magic boxes. I've been turning wrenches on outboards for fifteen years, and the chapter on understanding the system actually explained the 'why' behind a lot of problems I've always just fixed by rote. The trouble-shooting flowcharts alone are worth the price. I keep this on the workbench, not the bookshelf.

I bought this to help me decide whether to rebuild or repower my old inboard, and the selection chapter was exactly what I needed. It gave me a clear way to match flow and pressure numbers to my engine's requirements instead of just trusting the parts guy. The writing is dry in a good way, no fluff, just information. I feel a lot more confident ordering parts now.

It's a solid reference, but I was hoping for more detailed specifics on some of the newer high-pressure direct-injection systems. The section on those felt a little general compared to the excellent coverage of older, simpler setups. It's still a useful book for a shop library, just not as deep as I'd like on the cutting edge.

As a parts manager at a busy yard, I deal with the consequences of bad fuel pump installs all the time. This book is a great resource to hand to a customer to show them why we insist on certain parts and procedures. The maintenance chapter on checking amp draw as a diagnostic is a trick I had forgotten, and I've already used it twice this month. It's a bit technical, but the audience it's for probably already knows that.

I run a small mobile marine service and this paid for itself within a week. A customer's PWC was losing power under load, and the voltage drop testing section in chapter 5 directly led me to find a corroded connector that other shops had missed. This is the practical, hands-on knowledge that takes years to learn, all in one place.

The business opportunities chapter was a worthwhile read, even for someone not currently selling parts. It gave me a realistic idea of the margins and the headaches of dealing with cheap aftermarket stuff. The technical chapters are the real meat, though. The explanation of how vapor lock happens in a boat engine after shutdown was the clearest I've ever read.

I was hoping for more direct compatibility charts between different brand pumps and engines. The book tells you how to figure that out yourself, which is valid, but when your boat is on the trailer and you need an answer now, that's not always convenient. Still, the theory is sound and the troubleshooting is solid. It's a good reference, just not a quick parts catalog.
