i have a 55 powerdrive v2 and pull cranks (aluminum fisher 170 prohawk 17ft 90horse merc.)they only way to go to pull cranks ,but takes a little getting ure to for other fishing.mine will last about 4 hours pulling cranks so adding another battery and a battery switch will probally be in my near future upgrades.All i will say go for it i`m sure you will like it.
