let me tell you what i have i have a 150 black max 1988 mercury o,b, and was not happy with the performance then i asked the question that your asking and was told to put on a 15x17 prop i was turning a 13 1/4 x 19 now im very happy so its all in the prop size sorry about that when i go out there are 3 adults 235 ld 180 160 thats like 600 lbs or people plus my takle and gas i have a 55 gallon tank so i figure i must have 1000 lbs on board and i go top speed about 34 mph on my gps with bad bottom paint chips and old so im happy and when you hit the throttles it will throw you back i like that so a 150 yep its good more is better in my book but a 150 is a good choice
