I've fished out of the jon boat but never owned one. If you are
thinking about used ones try looking in the clasifieds of your
local news paper or a swap and sell it guide if your area has one.
Around here they use anywhere from a 9.9 up to a twenty five
horse on them. But, it still depends on how big of water you plan
on fishing on, and how far you are planning on traveling on the
water. Also be careful when buying a used motor as I would want
to see and here it run. Anyways Good Luck !
