What voltage and amp hour batteries are they? The AC and pump will draw 7-8 amps at 120 volts. Thats 70-80 amps at 12 volts, batteries are only rated for 50% discharge usually, figure 70% duty cycle and some loss due to inverter inefficiency and cable loss - dealer probably isnt that far off unless you have some pretty good sized batteries..

I am really a num nuts when it comes to any thing electrical. From what I can tell the two batteries are MCA 81, COA 650, and it said average minutes @ 23 amp draw is 225.

About an hour of AC at 100% duty cycle was a good guess for a pair of those, not enough battery for any real AC use - unless there is six more of them hidden somewhere :)

Hi, Anyone recognises a 280 -04 named Miss Gorbie II or similar from Beaufort, NC?

So, if Sandy wasn't bad enough, there's a nor'easter forecasted for midweek. I thought I'd get going while the going is good and have the boat hauled within the next couple of days. Well, I winterized the AC, genny, and freshwater system today, and I'll do the engine on the trailer. I removed the input to the freshwater pump and put the line in a 5 gallon tank of antifreeze, and the pump would not suck up the antifreeze. Luckily, I had a nice 12v Jabsco transfer pump, and I purged the system with pink using that. Does this mean that the freshwater pump is on it's way out? The water pressure was on the low side, and I'm wondering if it gave out altogether.

Does anyone know what size anchor rope and chain came with the 2003 280DA? The winlass is a lofrance marlin

My Kodiac plow has bent several times. Looking to upgrade to something stronger CQR perhaps. Anybody have any suggestions on what fits well?

[JimT]

I too would like to replace the Kodiak plow that came with my boat. It does not hold well in the thin clay mud we have at the bottom of Lake Norman. Anyone replaced with a danforth type?

Battery charging problem, installed 3 new group 27 marine batts. whats happening is port alt only charging approx 12-12-5 at first but after running and hr or so comes up to 14-14-5 like starboard motor, wondering if onboard charger is failing.what do u guys think??

[susanandlance]

I'm thinking a weak alternator on port engine, maybe bad diode??

Lance, I had a bad port alternator and changed it out. My Smartcraft gauge now shows 13.5v compared to 14.2 v on the starboard side. I checked and it's the same alternator as the old one and as the starboard side. I have yet to get a good answer as to why it shows lower than it did before.
