with fortrex 80lb pulls my RT188 3.4 with light wind. at 50, pulls it about 1.5 give or take a tenth.
I just purchased a new Ranger RP190 with an Ulterra 24v 80lb thrust trolling motor. Will be using it to both push and pull for crappie. When I tested it this weekend the most it would do was 2.7-3.0mph. There was some wind, wouldn't call it a stiff breeze but into the wind 2.7 was the max.
Just wondering if any of you guys with similar rigs (like a Ranger RT188 with Terrova) have any gps number on your top speed?
I won't be trolling that fast a lot but into the wind if the motor is constantly working hard I'm afraid the batteries won't last all day...

My 80 pound Terrova on my 1860 Horizon would pull 4.0mph in zero wind of current. My 101 Terrova on my Excel will pull it 3.2 with no wind or current. The Horizon was probably 1/2 the weight of the Excel. The 2 series 29 deep cycle batteries in the Horizon would last up to 7 hours if I wasn't bucking strong winds or current. Haven't fished out of the Excel yet but I rigged it with 3 Trojan 1275 golf cart batteries. I'm hoping they last from daylight till dark. We'll see.

Hull speed has a lot to do with how fast you can go with a given troll motor. My little Coleman Crawdad (12 ft)and get 5.1 mph with a 40# Endura. A 70# MK on this boat got me to 5.3 mph. Seems like you are flying in the Crawdad at this speed.

On flat water, my 24v 80 Terrova will go 3.1 mph up on Rabbit speed. That is on my Alumacraft Competitor. It is 17'11 long and 96" wide
Trolling walleye, I troll spinners at 1.1 to 1.3 and can get 8 to 10 hours on a full charge (that is trolling both into and with the wind).
I have group 31 sized AGM batteries from Cabelas and a ProMariner ProSport 20 plus charger.

70lb PD-V2 and 2 27 series interstates pulled my Bumble Bee bass boat at 2.4 to 2.6. Motor trim made a difference, of course. Never had my Batts fail to let me know what they would take. 7hrs at 1.3 and they were still going strong
Creativity is just intelligence fooling around
3 mph is the most I get out of my 80 pound on a Triton. There's probably nothing wrong with your batteries.

No one has asked what gauge wire you are running. Should be at least 4 ga.
My 15' aluminum bass stly boat goes 3.2 mph with a MK 70
