Re: What qualities and features to look for when buying your first trolling motor
I know you're looking for "cheap" TM, but you'll be better off buying a "digital" trolling motor. MinnKota says you can "go up to 5 times longer" with a digital motor, but realistically it's more like 2-3 times longer if you run the motor around 1/2 power. IE: you may only need 1 trolling motor battery instead of 2. Just spit-ballin, but running a 40-50# TM constantly at 50% power off a group 29-31 battery will last roughly, 3-4 hours for an old speed coil TM or 6-8 hours off a digital TM (rough guesstimate).
For fishing, are you going to be trolling, or positioning and casting? Personally, I like transom mounts better for trolling and bow mounts for casting. An Ipilot bow mount would would be great for both trolling and positioning, but they are expensive.
WRONG!!!
Most any of them will not push a 16.5' fibarglass boat from the rear even on a calm day with a 40# motor.
Are you sure about that?.... I used to run an old 43# MotorGuide on a 16.5' (
heavy soaked foam) SeaSwirl and it worked OK. Surely not setting any speed records, but it caught a bunch of fish trolling. It also saved me once when the main engine konked out and we had "troll" 5 miles back to the marina.
I'm not saying more power wouldn't be better, or that 40# will push the boat through waves/wind, but I'm sure he could do some fishing with a cheap 40# TM if that's all that the budget allows.
