I have found a 20' 48" aluminum fisher used for what seems a good price. The guy wants $1250 for boat motor and trailer. It looks to be in great shape but the motor is junk. The motor is an older 115 merc. That seems awful big for anything that is 48 wide. I have a good 100hp johnson with all the controls on a junk fiberglass boat that is 16' 48" and it really sat low in the water scary low when the river is rough. Does anyone know what this aluminum boat is rated for?
