Minnkota question

[Dano2]

I'm buying a minnkota powerdrive this week,
i have had 2 different suggestions from 2 different sales people.
I have a 16 ft. Bayliner runabout speedboat,
(my fishing unit).
I cant decide between the 50# thrust with the 54inch shaft.
Or the 55# thrust with the 48inch shaft.
I have been told that the 50# will be plenty becasue the longer shaft is what I really need to get down deeper in the water .
help.
Thanks

I agree with the longer shaft, with that boat 50 pounds will be fine. I had a boat that weighed more than yours or about the same and I had a 42 pound autopilot and I hugged shorelines in 5 feet of water against the rocks of leech with a 20 mile and hour wind with no power problems, it was a 24 volt so I never ran low of battery either. It could depend where you fish, if it's bigger lakes you'll need to keep the shaft in the water 200 pounds of thrust isn't worthwhile if the motors spinning in the wind!
