Got a great deal on a used 16 foot deep V smokercraft with 50 hp , council steering. Looking to get a trolling motor for the Detroit river to do some vertical jigging. gEtting a few opinions. I want to get a bow mount, went to the minn-kota site and put in all the info, and they are recommending a 70 lb thrust "power drive" (I'd like the 24V system ). My buddy says I may not be able to keep up with the current on the river with the 70 lb thrust . I'd also like to get the i-pilot link attachment, for when I do some inland lake fishing, but the darn "link" only is 799.00, on top of the 1179.00 price for the 70 lb thrust. The 80lb thrust Minn kota terrova is 1800.00, which include i-pilot link. Damn, I almost fell over when I saw the price on the terrova! But I have heard some great things about it. I'm thinking about saving for one, and it will probably be the last trolling motor I buy! My buddy says it will be easier to control the boat for vertical jigging with a transom mount, 24v motor . What size would be sufficient - 80lb thrust. Does anyone have any experience with a Minn Kota power drive or Terrova, bow mount, on the detroit river in a 16 foot boat? What about using a transom mount ? Any any and all input appreciated.
