put 3 ionic litthium ions in my ranger rt198. I can't get to 50mph anymore. Is it that much of a weight change that my boat can't hit that speed anymore?

Occasionally removing weight from behind the pad you lose bow lift, which hurts speed. YOu might get your prop worked for more bow lift, or swap to a prop that has more lift.
No pad it's a tin boat. Did you add a new 36 volt troller on the front or keep it a 24 volt? Do you have it set too high prop to pad?
i added the new garmin force trolling motor. Its pretty heavy. but i kept it a 24 volts. I have 2 small lithium ionic batterys for the trolling motor. Those two batterys weight 14.3 lbs each. The starter lithium battery weighs 34.2 lbs. The rt198 has a pad hull https://www.rangerboats.com/aluminum...nt/rt198p.html

The extra weight on the bow will definitely kill speed.
If when you are running and trimming up the motor and gaining speed to the point you run out of trim, you might benefit from some wedges to give you more trim. They helped my boat a lot.

What prop do you have on it now and in what holes are the top mounting bolts? What are the max rpm's you can get now?
drop the motor one mounting hole down.
You are losing prop bite, incrasing prop slip %.
How fast are you going now and how fast were you going before changing batteries ?
