Where is your structure scan and your 83/200 transducer located?  Are they being pulled out of the water when you start going up on plane?

I cant say for sure but I bet they are pulling out of the water.  The 3d is where I have mine and it does come out of the water.  I do this to keep from knocking it off at speed plus they wont read at speed either.

 

On the 83/200 Is that an aluminum or glass boat?  if its glass boat I'd epoxy it to the inside of the boat.  I do not know if you can do that to aluminum boats.  Almost all glass bass boats have the 83/200 in the bilge are of the boat.

 

In the OM look at page 20.  It will show you locations and pros/cons of each location.    You will also need to level the 3d transducer to how the boat sits in the water.  It will clear up your picture.

It’s a 2005 v-18 tracker. I had them installed by a marina and hope nothing is wrong since I know nothing about them. Is it common not to read around 4mph I thought most people could see there’s on 8mph and more

Put a flat board on the bottom of the hull extending out under the TD, the TD should resting on the board flat about 1/4" below the hulls surface. I would reverse the location of the TD's to reduce prop wash affects. You need a round puck trolling motor type TD to expozy inside the hulls sump area. The small TD should work on a plane.

Get 3M 5200 marine sealant to seal the holes and fasteners.
