John, i also have a 17' Mr. Pike and have 9.9 4 stroke mercury as a kicker. Seems to work fine for most of my trolling speeds, however, for the Bay type of trolling where they are using the Usiks at .5, I add a bag, otherwise, have no problem. What ever kicker you pick i would highly recommend the TrollMaster Pro speed control. It is a remote control run by a little electirc motor attached to the throttle rod and then the control is at the console, you can adjust speed a .1 mile per hour by a turn of the dial or instant full throttle if you need it. The link below will take you to the item at Cabelas, I bought mine directly from the maker but i cant find his website again. Believe me it is well worth the $200 investment, lots of the pros use it. Easy to install to. Best add on that I have on my boat, besides the 9.9 kicker.

I think you will love your new Lund, I know I love mine. Good luck. Feel free to contact me if you have any questions.
