Perfect for my Tracker Pro 160

The livewell pump in my 2013 Tracker Pro 160 was leaking. It was a Johnson 3850, and this Johnson 38503 was a perfect replacement!

very quite and efficient

works real well. I was able to make some adjustments and it came with some spare part to make it fit in the tight space i had for it.
