Trace the shaft fwd from the packing gland. If you have one, you will see it.
Thanks for all the responses. I am going to replace the cutless bearing. Does anyone have experience doing that?
" I did it without even having to remove the shafts."
sbman,That shaft pro tool looks great,but how do you get the new bearing on the shaft if you don't at least back the shaft out partway?
Slide it along the shaft from the aft end where the prop has been removed. If you have more than one bearing on the shaft, you replace the forward one first by sliding it through the aft bearing. A clean shaft and a bit of dish soap can help.
Any ideas?
Here are the two links:
Good examples of a "weird screeching noise".Greetings,
Mr. jL. A case of Billy Idol?
A friend's uncle had an affliction of Patsy Cline a number of years ago. He was crazy...
Thanks for the suggestions.
The noise is not related to the engines - the noise is aft of the engines near the props and rudders. I did scrape the barnacles off all of the underwater gear, changed the aft starboard cutlass bearing and the noice is still there. and it's only between about 1400-1650 rpms.

That's the same idea as long screwdrivers or socket extensions also help to pick up vibration noises from specific sources. Hold one end against your head, just at your ear canal, and the other on the suspected location. Much easier to pinpoint noises without the background of all the other sounds. But you're more likely to find dowels in much longer lengths. And maybe pull double-duty as a story pole to measure fuel tank level (just keep the messy end away from your head!).Along with measuring temperates I found using a wooden dowel 20 to 30 inches long to help ID strange noises. Put the dowel on different parts, water pump, alternator and so on and touch the other end to your ear and listen to the local sounds. (engine running) works great trying to find problems.
