Loud whine in driveline at low RPM

I have a 1974 A4 in an Ericson 35that runs great and seems to have few problems except when I am in forward at lower rpm and this 'whine' or squealing noise starts up. It doesn't seem to be coming from the transmission but more or less from behind the transmission (even from behind the stuffing box). When the boat was recently out of the water I checked the cutlass bearing and everything seemed OK there. When I increase the rpm's to cruising rpm the noise goes away entirely. Anybody have any ideas??

Thanks,

David
