    Yamaha 3.1 questions

    What is the difference between a 3.1 225 OX66 and a 3.1 200 OX66?
    will a 3.1 225 powerhead work on a 3.1 200

    I have a 200 and I found a 225 with low compression so I was thinking about buying it and rebuilding the power head for my 200.

    I called hydrotech a while back about mine and they told me the ecu and heads. they also said their stage 1 setup is a better way and adds about 40 hp
