Trolling Motor Loss Of Power

[Basstrackertx17]

So after a great outing the other day, I was noticing a change in thrust in my trolling motor.
Kinda the second time I was thinking about it.
So I went out in the garage and ran the motor on the speed I usually run. Seemed ok. But sound was off.
So ran it a little faster and it seemed to struggle.
Put it on hi and poof, it quit.
I had nothing.
So put it on constant and went to the battery.
Just touched the fuse holder and off it went.
So pulled the fuse holder and the fuse fell apart in my fingers

So it took me 15 min to get the end of the fuse out of the holder because of corrosion.

put the spare fuse in it and off it went.

Still didn’t sound quite right.

so I did a voltage drop test and got a .5V volt drop from the battery to a foot beyond the fuse holder.

Decided to cure this once and for all.
I installed a 40amp circuit breaker.

So no more voltage drop and she is singing like she should.
Will know for sure next outing but, I’m pretty sure she’s happy.
Just a tidbit of info.
There is a right and wrong way to hook up a circuit breaker.
Usually there is some sort of marking for “power” and “aux”,
Might be hard to see. Make sure if your circuit flow.
It does make a difference.

Yep....fuses are fading fast, more and more breakers are being used. Much easier to push reset than trying to reolace a burnt out fuse. On most of my toys, I have replaced the glass fuses with the plug in auto type square fuses, even that has made an improvement !!

Nice diagnosis and fix.

Test it on the water on full power. I tried that type once, but it was the auto reset type. After a little bit of high speed, it started acting like a bucking bronco. Used too small of a value.

TY
I have a hi speed run planned my next outing.
Usually, breakers are a little more forgiving.
After 28 years of fowling the prop solid at least half a dozen times a year and not
popping it, Im not expecting anything different with a same amp install.

Update on my issue.
Absolutely Fantastic….
Just like it’s suppose to…
Can fish in the wind again.
