  • 150 or 200hp for Mako 20b

    Currently in the process of refreshing a mako 20b. I have a good lead with a 150 etec g1, but before I pursue it I would like to know that I will be getting sufficient power. Anybody have a idea of what cruising and top speed I would get along with fuel burn?

    I have a 1975 Mako 20 that I installed a 2014 Mercury 150 four stroke. Should be comparable wot 43 mph @5900 rpm 17 4 blade prop average fuel consumption is 3.75 mpg. Plenty of power and speed. 150 will be fine

      A 150 will be fun.

      A 200 will be a lot of fun.

        This! I had a 150 on my 20c and it was more then sufficient but I always wanted a 200 for a little more "fun". [8D]

          I have a 150 2 stroke Johnson on mine and can touch 37 knots @ 6000 rpms glassed out. Most often cruise between 4000 and 4500 between 25 and 30 knots. If I were repowering, I'd prefer a 200 but wouldn't mind a 150 again at the right price.

            I just repowered my 20c with a 2005 Yamaha HPDI 150. I havent used it yet but I can let you know my numbers this weekend.
