My brother was hanging upside down, peering through a 9-inch square cutout in a bulkhead at the raw-water pump housing on his 3-cylinder Yanmar marine diesel. “How the heck do you get the impeller out of there?” he asked me.This is a very good question. Removing an impeller is something that should be done on a regular basis; Yanmar recommends replacing the impeller on this particular

Keep it simple

by Sail Staff, Posted June 17, 2009
The decks on Horizon, our Hans Christian 38, are 20 years old and have seen the full spectrum of weather conditions—cold and rain for weeks on end in Alaska and constant sun and heat in the tropics. No matter where we are, our maintenance strategy is the same: keep it simple and keep it silver. As with anything boat-related, proper maintenance now is always much easier than an extensive

Energy Control

by Nigel Calder, Posted June 15, 2010
Recently, as part of my work on hybrid propulsion systems, I attended a demonstration where a large-scale lithium battery pack was deliberately pushed past the boundaries of existing experience. The intention was to run the system at 20 kW of output and 160 volts, creating a current flow of around 130 amps. Owing to a miscalculation, when we threw the switch and brought everything on line we
Ever had refrigerator angst? It’s a dreadful state of mind that consumes you when your reefer doesn’t deliver the goods. It’s been known to paralyze cruisers for weeks on end, trapping them in exotic ports while they lay in wait for that rare, elusive creature known as a marine refrigeration technician.

Learning to Do It Yourself

by Dean Abramson, Posted January 10, 2013
I never used to read how-to articles in sailing magazines. They were too daunting. I might want to build a thingie or fix a whatnot, but a few paragraphs in, I would learn that success was possible only if certain conditions were met.

Bosun’s Box, from A to Z

Carrying everything from extra nuts and bolts to blocks and batteries could be essential to the safety of your boat. 
The phrase “out of sight, out of mind” is all too true where boats are concerned, and some of the systems that are out of sight on a typical sailboat can really ruin your day—or your season. Take the exhaust mixing elbow, for example—and give yourself a pat on the back for actually knowing what it is.

Gravity Theory

Smell. Pong. Effluvium. Whichever way you describe it, the airborne essence emanating from Ostara’s aged sanitation system was highly unpleasant. More than just an odor but thankfully short of a full-blown stench, it permeated the forepeak and almost caused a spousal mutiny during our first weekend aboard. No doubt about it – something had to be done.The sanitation system comprised a

Keel improvements

by Peter Nielsen, Posted June 22, 2009
Jabberwock, the BoatWorks project O’Day 25, was looking very scruffy around the underparts. The boat had been standing for so long that most of the paint had just fallen off the bottom, and the keel was looking particularly seedy. There was no way we could launch the boat with the keel in such bad condition. It was time for a makeover. A proper keel job done by a boatyard will cost

Filter Your Fuel Off-line

by Chuck Husick, Posted June 15, 2010
It’s essentially true that if you give a marine diesel engine clean oil, clean air and clean fuel, it will run, if not forever, then certainly for longer than you are likely to own your boat. Using good-quality diesel oil and changing out the oil and oil filter at the manufacturer-recommended time intervals—typically every 200 hours—is a good first step. Similarly, if the air intake is correctly
