Well guys, I got out for a couple of hours this morning. As you may recall I'm running a Minn Kota 55 lb. Endura on a 1648MV. I fish total electric 95% of the time. I don't troll. I move from place to place and fish anchored. With the wife and I and our gear the top speed on GPS with the stock prop is between 3.0 and 3.2 mph. With the new prop it was between 2.8 and 3.0 mph. Yep I actually lost top end speed a bit with this prop.
Why? Don't know. I've run the other prop since 2011 and the performance is very consistent. I ran off of 2 fully charged deep cycle batteries, same as always. There was no wind this morning so that wasn't an issue.
The prop ran smooth and seemed to have less vibration than the stock prop at speed. It has to be that my particular setup just doesn't benefit from this prop.
