Tom, When I put fuel into the Enterprise (insert dilithium crystal / antimatter joke here), I often have to go very slow as the fill will back up if I go quickly, giving me a false impression that the tank was full. Could that be it?
Also, is there any chance that the boat has a bit of a heel when fueling this time? I think, but not sure, the fill is on the starboard side of the tank. if the boat is heeled at all to starboard, the port side of the tank would have some air left in it. These are just guesses as I am also at a loss, and my usual solution to engine problems is “get the jib out.” All the best, Edd Edd M.

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. Tom B .¤º°`°º¤,¸¸,¤º°`°º¤¤º°`°º¤,¸¸,¤º°`°º¤.
