    Optimax V-6 3.0L 225 vs. Four Stroke V-6 3.4L 225 ??

    Considering a re-power of a 2005 Optimax 225XL with new Four Stroke V6 3.4L 225 on 22' center console (Whaler 22 Guardian). Will operate boat primarily in the mid-range in the Pacific Ocean.

    How should I think about the change in performance I will experience? Searched around the internet and didn't find much. Sure would be nice if Torque curves were available.

    Anyone have anecdotal experience they can share?

    Much appreciated,
    IC

    I have buds that went from optis to the 4s motors. 225 reg opti to the 225 4 s the optis got better fuel Mpg and performance Now the v8 225 are pretty equal in performance but the optis still put out better mpg. Both have their advantages. I still like the optis myself mainly due to the exorbitant cost of the 4s engines.

    Will perform as good or better all around on that boat (even low end and mid range) these new motors are insane. Fuel burn will.alsi be better.


    Alot of people are not prop testing g w8th G3 and it's really messing up the performance and fuel burn. I've had to re prop a few right from the dealer and it's amazing the performance they pick up
