I have not been raising the motor but will start now. I have the 45 inch shaft ( i think) but i do keep it all the way down. Considered the longer shaft but the way i had it mounted it would have stuck way off the side. (I didnt think about moving the mount).

Not sure how much it affects the situation, but i did notice on the charger that it says its for 90 to 135min capacity batteries and i think mine are 185 or maybe 205.
