Looking to upgrade the trolling motor on my 2000 G3 Pro 185. I’m running a 2000 Yamaha V4 115. Pretty much set on the MK Terrova, but I’m unsure if 55lbs of thrust will be enough. I normally fish alone and I don’t load the boat with a ton of gear. Also unsure if the 45” shaft is the way to go or if I should go up to the 54”. Any advice would be greatly appreciated! Thanks in advance! 

Looking at the ones I’ve seen for sale most are running 55 lb. if your running 12v I would go with it. If your running 24v and the price is right I’d go for a 80 lb. but it’s not a must have. What length shaft have you been running and did you have any issues with it being too short? 

If you are currently running a 12V TM and you don't want to add an additional battery then I would just go with the 55. Otherwise, I would step up to the 80. I can't say I have ever heard any say they wish they would have bought less of a TM.

I ran a 55 lb Terrova on my Triton x18. For 7 years. It does the job but struggles in wind and current to last the day.

I usually fished on 4 setting, but in harsher days 7-9. 
I just installed a 82lb 24v MG Tour Pro on the boat today. Haven’t used it yet. It is much heavier and much bigger than the Terrova so top speed will suffer. As I get older fishing has become more important than getting there 5 minutes earlier.

Bite your tongue.... JK ?????

I bought a Ranger RT188 and lived for exactly one season with a 12V TM.  I was so sick of losing the battle against anything but a light breeze that I replaced it with a 24V Maxxum before the second season.  Second best improvement I have made to my boat.  This winter I scrapped the Maxxum for a 24V Ultrex.  That's the best improvement I have made and I've only been out with it three times.  Game changer.  I can't imagine running a 12V on your boat where I fish, but if that's what you've been using on your lakes and you're happy with it by all means save your money for lures and rods.  

I bought the boat with an older model 24V Riptide that I believe was a Terrova model or maybe a different name but had the same features. Not sure of the thrust. Guessing 70 or 80lbs. All of the decals were gone by the time I got it and it never ran properly. The guy I bought it from said it has been giving him problems for a few months before he decided to sell it. I think it was actually a 60” shaft. Way longer than necessary for my boat. Spot lock/anchor mode wouldn’t work and even when I had it set on 10 it struggled pushing the boat. 

I installed new batteries and it didn’t fix the problem... hence the upgrade lol. 

If you already have a 24V set-up, 80 lb would be a no brainer for me.

look for a minn kota service center by you.  I bet they can get the riptide working.  riptide is the saltwater model.  Most walleye boats up north are running 60" shaft.  I have an 80lb 54" terrova on my 16.5ft Lund.  No way I'd go down to 12v 55lb especially with iPilot/spot lock
