Chris, I purchased the 2 and 3 battery tray from this vendor https://www.bassboattech.com/index.php/accessories/other-custom-accessories/trolling-motor-battery-trays
I have only put the three tray in my WX2200 I think the WX2060 is about the same size, I have 3 AGM group 34 batteries for my trolling I will be purchasing a lithium for the fifth battery to save weight and used for my electronics. With a little modification I think I can get three group 31 batteries in to replace the group 34’s in future if needed, before and after photos attached.
