I feel your pain, been there and done it.
Hopefully that's the end of it for you.
I learned the hard way, kept forking out on a motor and in the long run I spent more than it was worth 3 fold and when I did sell it all the work I had done on it didn't add any value. Next motor I brought was nearly new and suffice to say you get what you pay for.
🤞 for you and the motor.
I personally wouldn't assume they follow it at all, I'd only place a bait there if I actually saw them patrolling it or signs they patrol it.
If you do decide to fish it then if its like lakes that I've fished before there may well be certain pick up points along it and not just cast on it and catch. One of the lakes the bars were mainly made up of large stones (the size of your fist or slightly bigger) and a bite cast on this was very hard to come by but by leading about you could find areas that were made up of much smaller gravel and this is where your bites came from.
Just a bit of food for thought.
