How often do you run your bilage blowers? Do you just turn it on to cool it down then shut it off or do you run 100% of time in seat
In the hot weather, I run them just about all the time unless I'm crossing deep water. This time of year, I just turn it on every now and then.
They do seem to pull quite a bit of power. Maybe 3 amps or so. When I'm running at night with all lights on, I've got to turn the fan off or a light or two to keep the batteries charged. I've just got one 4" fan so two can make that problem worse.
I wouldn't be too worried about to though, the other evening I was running a 40" light bar, four 4" pods, bilge fan, stereo, and stock lights and the battery gauge started slowly falling.
