I have a puzzle. I was on my way to fill up last
trip out for a nice weekend rendezvous with out
club when I ran out of fuel. Fortunately, I was
close enough to our club in the inner harbor. I
dropped the dinghy and ran to shore to get a
gerry can of diesel. When I finally got to the
gas dock in Tacoma she only took 24.5 G of
diesel. I made sure that the filler tube was
open and even intentionally overfilled it to make
sure the vent was clear (than god for my catch
can!) I made sure the tank was topped off.
I have never trusted by gauge as it would show
empty when there was 1/2 a tank left. I used to
chart all time and distance religiously in my old
boat and did the same on Alera initially. Then I
realized that unlike out old 35 MK1 Alera had a
functioning Hobbes meter. So over the last few
seasons I got lax and instead of copious logging
I just take a picture of the Hobbes meter at
every fill up. Made sense and eliminated the
problem of accounting for sailing time on long
runs. Based on the Hobbes meter reading from the
last fill up the engine ran 26 hrs. Very
consistent with my established burn rate of 0.9 GpHr.
I started to suspect that maybe the PO had
replaced the original 40G tank with a smaller
one. However, when I checked my log book I have
had several occasions where the fill up was more
than30G.. Not many, but more than one or two over the 25G mark.
The rancor is clean and aside from need to bleed
the system down to the injectors to get her
started after the stall out, no air leaks in the
fuel system. Motoring in flat seas, so sloshing fuel is not it either.
Have at it C&C sleuths...I am at a loss.
