so my bf35a won't go pass 4,000 rpms while on the water. It starts and idles without problems but the minute give it throttle the motor starts to vibrate and as you start to increase the throttle under a load it won't go past 4,000 rpm. But the minute you caveat the prop it runs normal and you can feel a surge in power and runs fine at full throttle. Any ideas what wrong?
