Ok so I'm kinda new here and I have a questions for you guys. I mainly fish the missouri river around St Joseph MO and I am looking at buying a boat. My grandfather lives on the river I fish with him and my friends that have boats currently. I can use my grandfathers boat when I want but there is somthing about having your own boat and being able to use it when ever you want. I have been looking at boats in the 16-18ft range mostly center console. Here is the issue I bought a 28ft pontoon last year with a 84 merc 150 on it. I got this cheep and this motor is good so I would like to use it on my fishing boat problem is that it is hard to find a john boat rated for a 150. I have been looking at a 20ft seaark river cat rated for a 140 but since my 150 is older it is 150 at the power head and more like 130 at the prop. Just wondering what you guys think about these boats and a boat this big. My grandfather is against a 20ft boat says they are too big and yes he has had one.
