  • performance of 25' with single 225,250,300

    I am getting closer to the point of powering my '76 25'. I want to get a single that is a few years old. I was wondering if any of the 25' owners here might have some performance numbers. thanks

      talked to a guy at Gpt. harbor W/single 250 on a bracket. Claims to get 1.8gpg @26mph. not to shabby, but the did say its hard to steer the boat. Rough seas fishing docking ect. and didnt track very well. i've got T130's and steer like twin screws and tracks like Carl Lewis. getting 1.8-2.0 mpg 13.9-15 gph fully rigged. Go with twins,you will fell better when offshore

        While the Mako 25 will run with a single (max hp is 300), it's a better performer with twins.

        While the boat will run with a 225hp, it's more suited to a 250hp. A 225hp will work harder to push that hull than a 250 -- effectively cutting the life of the engine. Assuming Yamaha's 4-stroke 250hp is as solid as the 225, there should be a lot of OX 250 EFIs coming on the market this year. That engine isn't the most fuel/oil efficient, but it's a sold runner.

        Make sure you put the right prop on whatever engine you buy -- what works on one boat may not work on yours.

          Thanks guys for the info. I have been keeping my eye out for a 250hp OX, I have heard good things about them. I hope that after a year or two to close the transom, add a bracket and get some twins.

            Before I spent all them $ on a Yamaha I would do a search on the floridasportsman.com and see what problems folks are having with Yamaha.

              Alcedo,

              The problems you're eluding to are with Yamaha's 250 HPDI -- not the older 250 OX EFI.
