We took the boat out this weekend, the first time in about 4 weeks. Everything seemed fine until we accelerated upwards of 3500 rpms. There is a very loud continuous beep sound which seems come from the helm and coincides with a loss of power. I checked all gauges and the oil pressure, temperature gauge all seem to be within operating range. The one thing i did notice was low was the stern drive oil from within the engine compartment. Note reving the engine in neutral has the same results at 3500 rpms. Is anyone familiar with this alarm on a 215 sea ray before we call in the mechanic?
