  • Stupid Question!

    In the process of rebuilding a 200HP Yamaha, the specs are the same for a 150HP and 200HP Engine. What makes them different horsepower?????

    rbablitz,
    Ok, for a stupid question, I will give you a stupid answer, because I really don't know for sure - but here's my guess:
    I've wondered this myself on my 115 hp vs 130 - the specs are the same for them also. I would guess the carbs are bigger and the cylinders are ported bigger to allow more fuel/air to enter the combustion chamber.
    Maybe, another member can give us a better answer on this.
    Good luck,
    Ken K
