I think mines the 45lb thrust.  It’s on a kayak so it works great except in weeds.  It gets bound up immediately.

 

I ordered the mosshawg but it obstructs the stowing mechanism.  I was then considering the grass ninja with the adhesive tape, but some reviews say it struggles with real grass.
 

Now I’m looking at the Motorguide Katana replacement prop but I haven’t been able to find any reviews on its weed less performance...so I thought I’d ask here.

 

advice?

Check Solas prop, it supposed to be pretty good in quality for money. About 6 years ago my buddy was managing this company, hope I can help you with discount. 

My xi3 is 55lb, digital, variable speed and it takes a whole lot to bind it up in weeds/grass, especially when I have it set on "10". I believe the blade that came on it is called a machete.
