ok we went boat looking yesterday. Looked at 18' alumacraft Allwelded Jon with a 60hp Yamaha 4 stroke. Also been looking at G3 allwelded 18 footers too. Anyway i asked the sales guys about wheather a kicker motor would fit on the back or would i have to buy and install a motor bracket. He stated that the 60hp 4 stroke would do great slow trolling. Would slow trolling be hard on the bigger engine ?and would it go slow enough.
