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...

Sorry Joe, I can't help you. However, Ed Miller is one of the best Yamaha mechanics out there, and he's in your neck of the woods. Essex's area.

Thanks Marty, I called him before posting, he won't be around until 8/10.

Only a few days! I second Ed. He is the best. If you find a marine mechanic this time of year that can jump right on your problem that can't be good. I know the wait is frustrating but I'd rather be out of commission a few days then a few weeks and dollars before a sub par tech can figure it out!
