Trolling motors

[Stripedbass]

I'm looking put a minn kotta trolling motor with the spot lock on a 21 seacraft master angler. Does anyone have one and what size shaft and lb thrust.

Thanks pat

I posted a thread to in the "performance" forum on selecting a bow mounted TM for my SC 20 MA - see my final post below. I got a 60 inch shaft which worked well for my boat but would recommend a 72 inch shaft for your SC 21. Also get a quality installation with quality components. My lithium Iconic 36v 50 AH battery is now $1000 was $1500 when I bought it ! PM me with any questions .

The final story of my final choice of TM and battery system (a little long winded).

I got a Minn Kota riptide auto deploy Ulterra with spot lock, 36v, 60-inch shaft.
Took me a year to make my choice - I spoke to 4 guys with TM on SC 20’s. Two had MK Ulterra’s 24v, 60-inch shafts who were happy with both the power and shaft length. The other two guys who fish the same area I do (long island sound and CT rivers which can have some wicked rips currents) have MK 36v, 60-inch shaft, who recommended to get the 36v if possible (but 24v will hold most of the time).
All four guys said 60-inch shafts are fine, if the prop is coming out of the water you probably will not want to stay out for long any way!
I had already decided to go with a Lithium battery set up for space, weight.
My year SC 20 has an awkward sized fore deck which prevents getting close to a TM mounted at the front on the boats center line (best position if possible) - which makes an auto deploy TM a no brainer for a 68-year-old over a manual TM.
Being able to auto deploy the TM while being at the console controls and FF is very nice when close to rocks, makes moving to different spots easier. After using it, I am very happy I chose an auto deploy TM.

I have the Iconic 36v 50 AH battery, their dual 36v /12v charger and their 36v heavy duty aluminum battery tray which totaled around $2000.

So far so good - The single battery 36v battery is a very clean uncluttered installation - compared to (3) lead acid battery saves 100lb of (2) battery weight and space. A game changer for a SC 20. My single 36v battery install was the first for my marine mechanic (who is truly a master craftsman) - he was not overly enthusiastic when I told him I was going with a new-fangled single "lightweight 45lb" 36v battery but after the "simple" install he was impressed and thinks that is the way to go now. Another feature I really like about the Iconic battery is that it has blue tooth that connects to a app on my smart phone which allow me to easily check the charging status of the battery.

On my SC 20 I roughly estimate I will get around 20 hours + - of constant 36v TM use in 5 knot current. Most times I have used 10 - 20 % battery for up to 6-hour fishing trip but not operating the TM all the time - rough guideline. The smart blue tooth app to easily monitor battery usage is nice
