1. Determine your budget. 
2. TM with spot lock and the proper power for your boat.
3. Electronics compatible with the TM you’ve choose 
4. Batteries for your TM & battery for starting motor with enough 
      AH for your electronics and accessories. 
Good luck on your search and make it enjoyable. 👍
 
 
 
 

Did you put baking soda to neutralize what is there? Sorry to hear that sucks.

Lithium hub. Their batteries (Ionic) have been great. Their customer service is great. 

Just deploy them so they’re lower than your outboard. I’m sure you’re not going to try if the outboard will hit. Same thing I have to do to enter or leave my garage 

I would contact Minn Kota help line. I found a list of Tracker xl mounts for different trolling motors but none were for the Ulterra.

Nothing that a 20 ft. Hydrofoil wouldn’t fix. ?

For a lot less money than lithium batteries and solar charger you could purchase a super quiet Honda generator 42 decibels that only has a .5 gallon tank that runs between 3 and 6hrs depending on load. Heck one 5 gallon can would do 10 fill ups.
 
 
 

If there going to stay on the boat all the time I would use a neoprene rod sleeve and then slide that into a pvc tube with caps on each end. Maybe a little over kill but I’m always on the safer side.

Hard to beat having a good and trustworthy mechanic. ?

What gen helix do you have now? If your existing unit is a older version and your getting a newer version with mega SI/DI you should upgrade your transducer to the newer version for much better performance. Other upgrades would be if your going to be networking this unit with other units/ equipment.
