Thanks. All of that was helpful. Especially the prop information. I will go to bass pro and see if I can get a motorguide hydrilla hacker prop.
By the way, if I got a second motor I wouldn't run them off the same battery, I would get another battery as well. But I might try putting another motor on the front, I have been wanting a motor with foot controls anyway. I am always with two people so we should be able to work both motors.
My motor and battery now last as long as we fish, pretty much all day, and it never drains down too much.
I am just looking to get a little more speed, it takes forever to get to spots on the reservoire I fish on.
Thanks again.
