Hey malibu. I have a tournament 192, which I believe is essentially the same as the 190 you are referring to. The boat is 19 feet and has the dual console and bow seating with walkthrough window. In my opinion, and others will chime in, the 19 dual console Grady whites are heavly little tanks. Mine has a 200 hp evinrude ocean pro, and the motor is definitely not too much for that boat. I have heard that 150 hp with the Grady 19 dual consoles is pretty much the minimum hp you want to be at. Regarding the 20 foot overnighter, I think the same can be said. 200 hp would be preferred, but you would need at least 150 hp. Bear in mind, I do not have the 20 overnighter, so I am going by what I have heard. I think you will find that for either of the boats you are looking at, you will need more power than the 130 hp you have. Just my thoughts. I am by no means an expert on this stuff. Good luck with your search. Keep at it and welcome to the forum. I too am new here, although I followed along for a couple of years before I purchased my boat. Take care.
