I have 2 exide 31 batteries that I bought at the same time in January or so. G3 175 eagle boat using a terrova 80lb thrust with I pilot link. Trolling at 1.6 to 1.9mph going with and against the wind for about the same length of time and i was able to troll for 6hrs and 10 mins. Is this good, about average or ??? I do not have a digital charger but it is a minn Kota 210.
It's my first year pulling cranks so I have no reference points.
All answers appreciated.

OK, you should be doing better than that but a couple things come into play.
1) Are you raising the outboard most of the way out of the water? This reduces drag way more than you would realize.
2) How long is your trolling motor shaft and how deep in the water are you running it? Tin boats tend to sit higher out of the water and in my opinion really need a longer shaft on the troller than a glass boat, I run a 60 inch and rarely have more than 12 inches of it above the housing. The deeper the motor is in the water the better the leverage it has, especially into the wind.
A good point of reference is, my boat is mostly likely twice as heavy as yours, I am running a 36V 112 but I can troll well over 9 hours on a windy day.
I have not been raising the motor but will start now. I have the 45 inch shaft ( i think) but i do keep it all the way down. Considered the longer shaft but the way i had it mounted it would have stuck way off the side. (I didnt think about moving the mount).
Not sure how much it affects the situation, but i did notice on the charger that it says its for 90 to 135min capacity batteries and i think mine are 185 or maybe 205.
Raising the motor will help, is the charger showing fully charged?
It shows fully charged but it takes a while. Both the charger and the meter on the terrova show fully charged.

Meter on the Terrova is crap, with a 210 charger you aren't charging but at a rate of 5 amps on each battery. Check the voltage on each one at full charge and double check the water level in the batts
Will do.

Sounds about right to me. Rees has another battery to discharge. Umbrellas create drag too. I raise my motor and troll downwind as much as possible and 7 hours or so is about it.
I did have both umbrella up today.

Well I can tell you this about the brella, I was trolling in the other day, dead calm, had the 112 cranked up to 8.5 and was running 3.1 mph. When I folded the brella up the speed went up to 3.3 and bumping 3.4 some, brella makes a pretty good drag but I wouldn't do without it.
Running your Terrova 80 at 1.5mph into the wind, say 8/10mph takes a setting of 6-7 or more on your gauge. 6 to 8 hrs is all you are going to get. This includes going with the wind 1/2 of the time. My 2cents
Prolly a good theory tooQuote:

My group 31 Exides would run my 80# Terrova for about 7 hours at 1.6 average with moderate wind when they were new. Now at two years old I'm lucky to get 3.5-4, less with 10 mph wind. If I can figure out where and how, I'm installing these two Trojan 1275 today. I'll report how they do while new.
O, well, maybe the acid won't leak out before I can get them in the boat.
So, when I got the Exides out the sticker says shipped in 2013. I haven't had them that long, but as the frog says, my how times fun when you are having flies.
the Trojan has the same foot print, just about 1 1/8 inches taller.
i sure have to put my thinking cap on, but u can bet they will be connected to the TM.
good grief. They loaded them for me and now I'm trying to pick them up and get them in the boat. I may need help, they are at least 25-30 pounds heavier. At least they feel like it..
now i can see what your sayin

They weigh right at 100 pounds, I slipped putting one in the Cat one time and when the dust cleared I looked like I had been on the loosing end on a fight.

I know they way too heavy for me.. Glad my number two son stopped by at the right time.
Gene, Be careful, I know how old you are. That's what the sons are for. I envy anybody that can troll all day in this heat- 112 heat factor today.
I will Scott, thx. I also envy someone that can stay out there too. I'm just shooting for 4 or so hours and I'm sure these new bats will do that. And too, I think they will tire me out later when it cools off some.
I tx the son and said ' what's going on' and he said he was coming by to see how I was. I said u must be clairvoyant
Trojan all the way here gene. Mine are 2 years old and still troll as long as I want to fish just ask Reese guide.
I have found that by not putting the trolling motor all the way down I could get more speed. That's on a tin boat as well. A good test would be to drop it all the way down and run it on rabbit. See how fast your running and then pick the motor up a bit and test it again. I would be willing to bet there is going to be a midway spot that you get the most speed, and to me that's gonna help you save some battery.
I was curious about if the trolling motor companies offer different props for maximum thrust and efficiency under different conditions and I came across this site.I don't know if any of this info will help but they have a page where you can ask questions and get answers about most brands of trolling motors, batteries, accessories.https://www.trollingmotors.net/blogs...tibility-guide
Found a company that makes replacement props for trollys that claim higher performance. Kipawa Weedless High Performance Propeller Catalog - Kipawa Propellers
I've got one of these props for a Terrova 80. I couldn't tell there was much difference but I didn't do any real comparison. I just tried it out for awhile. I still have it, but I just use the factory prop with the Golf Cart batteries. No problem for as long as I want to fish in this heat.Quote:
