The 190 and 195 are same length, with the 195 being a little wider and just slightly deeper. It also weighs 167 pounds more according to Tracker's web site. I am seeing alot on here about 150 HP engines on tin boats of various makes maybe not being a wise choice considering the 0.100 hull. I know people say it is good to go with max HP, but what do you think about using a 115 engine on the 195? The 115 is max on the 190 and there is so little difference the 190 and 195.
