I have a Minn Kota Riptide with a 55 lb. thrust hooked up to a 12V battery. The motor has forward speeds 1 through 5 and reverse speeds 1-3 (I think). Recently, I noticed the motor was not getting as much thrust on five and figured out that I only have speeds 1 through three in forward, and speed 1 in reverse. I contacted a Minn Kota dealer and they just said bring it in but I know some of those places can charge mucho $$$, any ideas?<br /><br />Thanks<br />Kevin
