Can anyone tell me how the shaft lengths are calculated for terrova motors? I'm upgrading my old evinrude trolling motor to a terrova and am wondering how they measure their shaft lengths. is it measured from where the head unit and lower unit collars start? or from the center of the head unit to the center of the lower unit? or some combination? my current motor measures 45 inches from the bottom of the head unit collar to the top of the lower unit collar. but is like 50 inches from the center of both. wondering what shaft length to get. the ipilot comes in 45 or 54 inch lengths. I don't mind going with the 54 if necessary but would stick with the 45 if it's the same length as my motor. my current motor is of sufficient length even in rough water. any info would be appreciated. thanks guys

If you have a 45in shaft now, and do not have blow out even in rough water you would probably be ok with a 45 on the Terrova. However, I would suggest a 54in. I am guessing you might be planning to run the Terrova from back of boat if trolling, etc. Right now, your TM when deployed, you are using the entire shaft in water, and the head unit is probably just above the front deck. A 54 in shaft would give you the length but also will allow some extra inches and you can put the head up higher above the deck making it easier to see the head from the back.

Minn Kota has a reference chart for selecting shaft length.

I think you're right ozark. I also decided to go with the 24V instead of the 12V. but it appears you can only buy the 24v with ipilot in 45 inch or 60 inch shafts. now I don't know what i'm gonna do

go with the 60 and use the stop collar for the depth you need. you cant make the 45 longer!

Agree. Put the longest shaft on that will stow without overhanging the boat. You can't buy too long, only too short.

I might just stick with the 12V 54 incher with 55lb thrust and do 2 batteries in parallel. I don't think the evinrude trolling motor that I'm taking off has 55lb thrust so it'll still be an improvement

They do come 24V in all shaft lengths.

EyeKing, Stratos is going for the Ipilot, and for some reason (known only to the marketing VP for MK) MK only offers the 80 Ipilot package with only 45 or 60 in shaft. But they decided to offer the 101 Ipilot in 54 or 60. Go figure---

Stratos' only other option to get Ipilot with 54 in shaft would be to buy an 80/AP/us2 in 54in and then have to buy the Ipilot for an additional $450.

I know that is an option and I'm considering it. but it certainly isn't very cost effective. the cost would be similar to buying the 36V but only getting the 24V. might as well buy the 101 and just run it on 24V

However there is an IPilot 55lb with 54 inch shaft that the OP prefers, right?

I think that is the direction I'm going to go. I think the 24V is more than I need. If it was available in the 54 inch I would get it cuz it's only a couple hundred more, but I think I'll be fine with the 12V with 2 batts in parallel. Thanks for all the input guys
