I have an 05 Yamaha F250. It suddenly developed a loud whine, only when in gear, increases with increased RPMS. Tops out at 5200 RPM's. Dropped lower unit, greased shaft. I checked lube, was burned, very thick, and only a couple ounces.. No water, or chunks of metal. Exhaust seems to be loud.. It also seems to be idling rough... Any help would be greatly appreciated...

Thanks
Joe Walsh...
