Recently acquired 225X will not rev past 3500 max in neutral, and will not get boat on plane. It idles very smoothly but makes no power. The oil level in the oil tank on the motor was low, but the cap was opened and it was then totally filled. There are no alarms at all and the smartcraft gauge doesn't indicate any problems. The battery is new and shows about 12.4 volts prior to starting the motor, and about 14.2 after the motor is fired up. My son and I spent the whole weekend trying to figure out what's wrong with this motor after a 100 mile drive to get to the water. PLEASE HELP! This motor had recently been switched from one boat to another by the previous owner. Any thoughts?
