Where most would think the “fun” weekends are the ones cruising hundreds of miles, sometimes it’s just as enjoyable to stay in the slip and do maintenance. This was a Captain-only weekend, to address minor maintenance-issues including lights and NMEA2000 sensors.
Christina received a new bow-light this weekend, after having been pulled-over a couple weeks prior for an issue that kept coming back. The original fixture held a festoon-type bulb, which uses spring-contacts to hold the light-bulb in place. After repeated repair-attempts to the spring-clips, it was finally time to replace the entire fixture… with an LED-type bulb. The captain also intended to install side-marker lights, however a recess in the flat-part of the bow prevented a straight-forward installation. The side-markers will be attempted again this winter in dry-dock, but Christina is fully legal now as-is.
Now that the Rose has the Mercury MercMon Smartcraft Gateway installed, the second area of maintenance planned for this weekend was removal of the two Garmin GFS10 fuel-flow sensors from the NMEA2000 network, now duplicated by the MercMon. What sounds like a simple problem to fix took over 7-hours to execute, as the time-consuming task to undo all of the intricate sensor-installations from a few months ago required complete removal of the aft deck to access the sensors and wiring.
Since the Garmin GFS10’s basically matched data from the Mercury SmartCraft fuel-flow, a few months of operation confirmed the GFS10 sensors’ accuracy and operation on the NMEA2000 network. Rather than just remove both fuel-flow sensors (because the Garmin GPSMAP 5208 has been reporting twice the fuel-usage since installing the MercMon), one of the GFS10 sensors was installed on the fuel-line supplying Christina’s Kohler 5E 5KW generator.
Once installed, the Kohler was fired-up and fuel-flow data was collected. Without load, the generator appeared to fluctuate between 0.2gal/hr and 0.3gal/hr. Once fully loaded with stove, hot-water heater, and A/C, the generator seemed to maintain 0.3gal/hr. It’s worth noting that Garmin claims the GFS 10 isn’t accurate below 2gal/hour, but it’s also worth noting that this sensor compared to the 6.2L SmartCraft fuel-flow at idle of 0.9gal/hr.
Total cruise-time this weekend was 0.0-hours, having never fired-up the engines. Total time aboard was 48-hours, most of which involved some-form of enjoyable maintenance.
