Hi all - new PWC owner here. 2 Yamaha VX 2015 USED. I've read that if I'm storing them outside (Shrink wrapped) here in New England that I should remove the batteries and keep them on a trickle charger? Is that right? If so, I found this one on Amazon: https://www.amazon.com/gp/product/B0...k_ql_qh_dp_hza

What do you all think? I'm probably going to have the dealership winterize them for me. Anything particular I should ask regarding this?
