Here are some of the amperage draw specs from MinnKota;

55# thrust--------50 amps @ 12 volts[600 watts] [10.91 watts per # thrust]
65# thrust--------38 amps @ 24 volts[912 watts] [14.03 watts per # thrust]
70# thrust--------42 amps @ 24 volts[1008 watts] [14.4 watts per # thrust]
74# thrust--------45 amps @ 24 volts[1080 watts] [14.59 watts per # thrust]
80# thrust--------56 amps @ 24 volts[1344 watts] [16.8 watts per # thrust]
101# thrust-------46 amps @ 36 volts[1656 watts] [16.4 watts per # thrust]

Hey OBG are these amp draws at max power?
That's MinnKotas specs. Should be maximum amp draw at however they tested/rated the trollers. I can't make any of mine draw that much but my boat is light.

How do these amp ratings compare to the size converter needed? I guess what I want to know is: Would you use the DLS 45 or 55 on the 55lb thrust troller? You mentioned that you haven't been able to make yours draw what is listed. So is DLS55 amp too much for a max draw of 50 amp and/or is DLS45 too little?

The converter only puts out what your troller is using--if you are going slow and your troller is using 20 amps the converter only supplies 20 amps. Converter input is directly proportional to output so it doesn't use more of your genny's output to run a bigger converter. A DLS-55 would be better because converters are less efficient as they reach maximum output.

Do you about how many amps a 24 volt converter pulls
There are several 24 volt converters but:
A DLS-27-40 should pull around 11.33 amps @ 120 volts[1360 watts] when it reaches it's maximum output of 40 amps @ 27 volts.

Makes you wonder how switches hold up as long as they do! Those are some serious amp draws!

Add in aging equipment, weeds, poor or undersized wiring, etc., and you'll be using even more than you might have expected!

Looking at these different amp draws on trollers, would one of the lower amp/wattage trollers be more efficient? How does all of that play in? Boat size would a a factor?

I added watts per # thrust to my original post. Those are MinnKots specs and I don't know how they arrived at them. How hard the troller has to pull definately effects amp draw and I'm guessing those are max amp draw figures since I haven't been able to make either of my trollers draw the amps shown. I will be running some more troller/converter amp draw tests when it gets a tad warmer.
