After a couple of hundred guys buy it and try it...then I'll consider it.
Anything that sounds too good to be true...almost always is...too good to be true.
No brand name. No source for props. etc.
I am particularly sensitive to this issue because..I bought a 20-year-old boat a year ago.
It had an Evinrude trolling motor on it. The TM worked fine. But, the prop was beat-up when I bought it.
The prop broke. Only then did I find out that
#1. Evinrude props ran backwards, precluding my using a modified Minnkota prop. #2. that particular Evinrude prop was out of production and couldn't be found, at any price, anywhere at all.
#3. I bought two other Evinrude props off of Ebay and neither fit.
#4. I wound up replacing the entire fully operational ($400.00) trolling motor because a ten dollar prop broke.
Let me know how this one works for you after a couple of years.
