    okay...looks like that old 21B needs to be repowered.

    The members on this iste have a geat deal more experience with this sort of thing so please give some advice.

    Right now I am running a 175 Johnson on five cylinders

    Weight is an issue but I would also like to have the power for this heavy boat.

    I am looking forward to reading your replies!

    Most of the guys down here are running 200s on their 20s and 21s. There isnt enough weight differance to even worry about. Good axample, I went from a 140 4 cyl to a 150 6cyl the weight differance is only 85# That is about the same weight as beer and bait for a day of fishing.[]

      Got to agree with Gary -- a 200hp is the only way to go.

      The 175hp is a good option on the 20' Makos -- but with the added weight on the 21B a 200hp is the best option. You won't work the engine as hard and for purposes of resale, it'll be a much more attractive package with a 200 on the transom.

      Good Luck,

        Can you ever have enough horsepower? You didn't mention how old the 175 is. Newer motors generate more power quickly, and use less fuel. I agree with the is more economical to run a larger motor easy than a smaller motor hard. Tony

          I stopped at Bass Pro this afternoon for a driving break...Makos were in the parking lot so I took a gander at the 22 OptiMax.

          Wow, that is one big motor....

            Has anybody ever seen a 4 stroke on a 21B? The 200/225's seem so heavy and I have never seen a 21 with a 150(2 or 4 stroke) on it.
