    why 3.0L 4cyl when you don't see that in automobiles?

    Hopefully this is ok to post here...<br /><br />Why do you see a 3.0L 4 cylinder boat engine, but never a 3.0L 4 cylinder car engine? Most 3.0L car engines are 6 cylinders. Is there a reason why you see this in boats, but not cars?<br /><br />Just trying to educate myself...<br /><br />thanks.
