Trolling Motor Thrust Needed for 19-Foot Boat

I want to add a trolling motor to the stern for fishing the intracoastal. Not sure what thrust to use for a 190 OUTRAGE. I would like to keep it a 12 volt system if possible and around 50-55 lbs. of thrust so the battery will fit under rear removable seat. I am not using [the trolling motor] to fish any tournaments, just some weekend fishing. Would 50-55 lbs. of thrust be enough?

It would be interesting to hear of any algorithm or relationship between boat length and trolling motor thrust. I have never seen any expression of this relationship. If there is a formula, I would very much like to see it and to understand the relationship it expresses. This is more of a PERFORMANCE question than an electrical one, but in as much as the motor is usually an electrical motor, let's proceed here in SMALL BOAT ELECTRICAL with this discussion. Thanks.

My bow mounted 24 volt Minn Kota w/ 65 lbs of thrust, pushes a classic Outrage 18 (which I'm pretty sure is lighter then the 190) around all day without any problem. IMHO I would consider this the minimum amount of thrust though and would have been looking for more if I hadn't got such a good deal.

I'm curious! Is there a specific reason why it has to be mounted on the transom versus the bow? It seems the best manuverability comes from the bow mount. Does the transom mount require more thrust than a bow mounted motor?

I don't think it will fit on the front of my boat due to bow rail, also i would like to take it off easily when not needed.

19 is a big boat. I would think you may need to be in the 24 volt 65 lb thrust range. It also takes more power to push and control than push. I am in a similar dilema on my 17 katama. Want to keep my bow rail but a bow motor may require a cut. I currently use my 30 lb 12 volt since I dont have another motor at the moment. It really struggles but it moves it and barely swings it with handle clearance.
