Still Crazy After All These Years?

Still Crazy After All These Years?
In order to publish test data that’s as accurate and complete as possible, PMY continues to flow fuel on small diesel engines...like the ones onboard Mainship’s new 34 Trawler.
 
 
 

Over the past few years, the advent of electronic diesels has largely, but not entirely, erased an time-honored PMY tradition—what’s known in boat-testing parlance as “flowing fuel.” In a nutshell, the procedure consists of breaking open supply and return lines on a given diesel engine and splicing in transducers that, when hooked up to a computer, give an accurate measure of fuel burned at any given rpm.

Not all engines have gone electronic, though. As you see here, some of the smaller Yanmars must still be approached in the old fashioned way, at least from the fuel-flow standpoint. And although Capt. Bill Pike has absolutely no love for the diesel-fuel baths that typically accompany flowing fuel, he’s still doing it in order to bring PMY readers accurate information on all the boats they’re interested in, not just the ones with electronic engines.

Above, he’s shown in the midst of a fuel-flow gear install on Mainship’s latest and greatest—the new 34 Trawler. Besides recording accurate fuel-burn data on the new boat, Pike recorded speeds, running angles, and all the other parameters that are part and parcel of all PMY tests. Moreover, he ran the boat in the Manatee River near Bradenton, Florida, and docked her afterwards, For Pike’s take on the new 34, as well as some nifty new photography of the boat, catch the January issue of PMY.
