Offshore Log: Thoughts on Engine Spares For Cruising

Emptying out the spares inventory for Calypso's Perkins diesel was an eye-opener—there were plenty of parts back-ups, and, in Nick's view, all for the best of reasons.

The engine mounts on my Perkins M20 diesel needed to be changed. Luckily, they are accessible so I was able to change them myself with a few basic tools and new parts. If your engine is less accessible, you'll need to ask a professional to change the mounts. (Photo/ Marc Robic)

Compression tester set up for testing. The hose is screwed into a glow plug hole after removing a glow plug. Note: This is a mock up to illustrate the tester placement, but this is a tester for a gasoline engine, not a diesel because it only goes up to 300 psi. A diesel tester would go up to 1000 psi. Also, ALL of the glow plugs should be removed, not just one. In addition, the hose is not actually screwed in because the fitting is the wrong size. (Photo/ Phil Decker)

Irwin Citation 34 Used Boat Review

The Irwin 34 is in many respects a typical Irwin boat. It was originally called the "Citation 34," which was meant to indicate that it was more of a plush cruiser than the race-oriented Irwins at the time, but more of a racer than the larger cruisers. According to the company, 305 Irwin 34s were built in the production run, from 1978 to 1985, a moderate but successful model for the era. Near the end of its production, the boat was advertised as the Irwin 34 rather than the Citation 34. There were no major changes in the boat from beginning to end, just the details and equipment that are typical of any long production run.
