Where to begin, a lot of differences between the two yet still somewhat similiar. I will just start naming things.
mx
7.25′ center rod storage
shallower front compartments, bow sits lower in the water
front deck smaller- gaining cock pit space
single or dual console
under console shelves standard
extra large glove box (dual console)
port side rod holster- one piece 13′ rods fit Lockable
starboard side storage, lockable
all 3 batteries in rear of cockpit with charger
NO jump seats,
50″ rear livewell
storage on both rear sides of livewell
extended rear casting deck
rear seats you can sit sideways facing the gunnel and not hit your knees
keel is much more aggressive than anything else out there (slow trolling and drifting you will go straight and not move with the wind)
Designed with the river fisherman, smaller lakes, and multi-species people in mind.
WX
larger front deck
Very deep and large front storage areas
7′ center rod storage
TM batteries and charger under rod storage
dual console only (bubbles or full windshield)
1900 1990 2100 have snap out carpet and possible under console shelves
1850 no snap in carpet and no shelves
side storage in cockpit with 3 lockable doors
rear jumpseats
Boat sits a little higher in the water compared to mx
Designed for big water fisherman (great lakes) and family friendly boat deep cockpit area and factory ski pylon option.
Now with all that said, both models of boats with catch just as many fish as the other one. There are goods and bads on all boats depending on the persons needs for a boat.
I know everybody says it BUT do yourself a favor and at least look at a wx and mx side by side and also drive them both close together.
After all that you should have a pretty good feeling of what boat would fit you better.
