  • Fuel economy mako224 2stroke vs4stroke

    I have an 84' mako 224 powered by a1998 merc 250 efi. I'm averaging around 1mgg running offshore. Most stuff I've read says that's about right with that engine on that hull. Ide like to see what others are getting with 4stroke power on the same hull. I'm looking into new power either a Suzuki or Yamaha 200-250.

    I have a older 96 Johnson 225. I am averaging 1.85 MPG. I have heard 2.8 with a 225 four stroke.

      Yea my trips have varied. On nasty rough days offshore not making good speed I've gotten under 1mpg. But on days calm inshore just cruising I get closer to 1.2 mpg either way nothing great. I was just curious on how much better a 4 stroke is

        The EFI's are thirsty, for sure. I have a 225 EFI on my 230, and I do a bit better than you at 1.3-1.5, it was at 1.7 before I added a hard top to the boat.

        My guess is that going to either a DI 2 stroke, or 4 stroke you would be looking at mid 2's or better.

            I have a m231 but essentially the same wetted surface i believe. My best cruise is 2.4 MPG with a 225 four stroke.
