Thanks for your response and yes,weight is a concern. What is hanging me up is the suggestion of going 24v and using small batteries like a pc 1200 compared to a 12v system with a group 29. Won’t I give up a lot of run-time? For the time being I am sticking to flood and agm’s Until I decide how much I will actually use the TM. Not ready to go lithium until I get more experience. Bottom line I would like to go 12v to keep the weight down, system install more simplified and keep the cost down to get started but I have had 2 dealers tell me I am wasting my money and I will be so much happier with the 24v. That’s the reason why I took the approach with the thrust to better understand the recommendation. Thanks again
New trolling motor decision
I am considering adding a TM to my Maverick 17 HPX-V. After speaking with several very reputable installers, most suggest the 24v system which I agree is the safe way to go but to keep all batteries in console I would need to reduce the Reserve min to 80-90 [email protected] Amps for the battery sizes to work.
A 12v system would be the easiest install and I have not ruled that out as I could install one grp 29 battery and get 210 RC min’s
Here’s where I could use help.
Different conditions require different amounts of thrust so to provide a simple comparison, the 55# MK draws 50 amps at max which will burn through a RC 120 battery in one hour. If I go 24v, the MK 80# using 55 lbs of thrust uses 38.5 amps based on 56 max amp draw x 69% of max thrust. In other words, if my math is good, the 80# motor requires roughly 75% of the amps to achieve the same thrust as the 55# motor. I am using terrova numbers here.
When I read comments like “if you fish in wind and current then go 24v” doesn’t that simply translate to more thrust for longer?
It would be great if anyone with my skiff would respond and/or anyone who would set me straight on what I am missing in my analysis.
Thanks

Thanks Vertigo. Saving weight and having good results is where I am trying to go
I am in Charleston, looks like you are as well. I have never owned a TM so not sure yet. I flyfish a good bit around the low tide and many times solo I am hoping that by adding a TM I will cover more ground
Thanks guys for all for your feedback. It sounds like I can realistically get 4 hours or more with a 12v system using grp 29/31 battery and keep this simple and reliable.
I really appreciate how quickly and thoughtfully you all have chimed in. What a great resource this is.

Tjtfishin and elusive porpi. Are you guys still running agm house battery and only lithium for TM’s? If I went 12v and wanted better performance than a 100ah/200 RC min group 31 battery what size lithium would do that. If I didn’t misunderstand it sounds like I could go 1/2 the ah rating and outperform. That would be huge. I did not realize lithium’s were priced there, would you be willing to share your source
Thanks
Thanks
PV redfisher. Would you mind specifying what size odyssey house battery and how you are recharging them? As an update I spoke with a guide here in Charleston this morning who runs a pro w/70 LA and he has the MK 70/24v and uses the pc 1200’s and says he easily goes 6 hours chasing tarpon. Can I assume you also have the 70? And are you recharging house off O/B and TM’s off battery charger?
Thanks and thanks again for those new comments

A quick update and again many thanks to all who have contributed
Jay.bush, essentially you have what the dealers are recommending and while I would like to go with the 12v 55#, I feel like the 80# 24v will insure a one and done decision
Btw what is your house battery and how do you recharge? Stealth or otherwise?
As a battery and motor update for the groups benefit, I spoke with Odyssey and asked about the PC1100 which weighs 27# vs 1200 @ 38# and with more juice and they claim it is a result of a different plate design and it’s also constructed in the UK unlike the 1200.
A local guide who will demo his setup for me after the holidays runs the 70# MK 24v w/ pc1200’s and suggests that motor for its weight. I called MK and yes it’s 45 lbs vs 65 lbs for the terrova 80# Apparently the deployment device and components are the reason. Also to get I-pilot with jog feature almost at same $
I don’t plan to make final choice until after the demo but because of all the good feedback it’s great to know I have the option to go 24 or 12v and get all the juice in my console with agm’s.
If anyone is in the Chas SC area and has the 55# setup with I-pilot and would be willing to demo I will be happy to return the favor...
Hope everyone has a Merry Christmas and tight lines!
