What pound thrust should a guy look at for 16.5ft mod v Jon
Plain and simple..buy as big as one you can afford.
If you dont boat in heavy current a 55lb is affordable and will work,but if you boat in somewhat heavy to heavy current get one as big as you can afford like an 80lb.
I have a 70lb on a little 16′ Lund. On the Mississippi it seems to be perfect for me. As others have said, go as big as you can afford. I personally would never go back to a 12 volt system just because with the 24 volt I have so much more run time so wind and current won’t ruin my day with dead batteries.
