For people concerned about losing fuel flow to their sailboat auxilliary engine while underway due to a clogged fuel filter, the FilterBOSS looks like a promising solution. The FilterBOSS can be ordered as a stand-alone unit ready to be plumbed into your existing fuel system ($950), or as part of a pre-mounted system containing your choice of two Racor filters (various models available). The unit we received for review was the 500FG Dual Filter Package, which includes a FilterBOSS with wiring harness and two Racor 500FG filters mounted and connected with rigid tubing on a pre-drilled, composite panel ($1,565). It features Type 1 copper tubing (.035-inch wall thickness), Bi-Lok CA360 grade brass fittings, heavy-duty valves (with Viton seals), and a Con-X weather-tight cannon plug for the wiring harness. The system also allows a convenient way to polish your fuel and rid it of debris that may clog your fuel system

The main drawback of thermoelectric coolers is power usage. This will likely be an issue during extended use or for boats with small battery banks and anemic charging systems. The 106-130 amp load, over a 24-hour period, is about twice as much demand as a built-in evaporative sytem and about three times the demand of the most efficient-and most expensive-installed systems. Also, thermoelectric units are limited in their ability to cool internal temperatures, usually to a maximum of about 40 degrees below the ambient temperature.

The best way to get all of the oil out of the engine (after a thorough warm-up) is to drain it from the plug at the bottom of the pan. In boats, however, its often tough or impossible to get at that plug. The optimum solution is to have an oil-change system permanently installed, with a hose from the oil sump to a bulkhead-mounted pump.

It was mid-July 1990 on the Caicos Banks, a stretch of shallow, gin-clear water extending for about 70 miles east to west in the Turks and Caicos Islands. Along with a dozen other cruisers whod chosen to thumb our noses at hurricane season (ah, those were simpler times), we were pausing in Providenciales before heading south. …
