I just changed mine after 43 years. The rubber inside came loose from the
bronze. Sea Cure had them in stock OEM.
I was able to make a press to remove the bearing without pulling the shaft.
They make a tool for $700 that does the same thing.
It was trial and error until I worked out the bugs.
The new ones went in with another home made tool in about an hour.
Thanks
Rich

Just got back from a month out boating. Great time (retirement boating is the
best) One issue arose. Just before we left and for the first couple days of
our trip we could hear both cutlass bearings squealing when the prop was free
wheeling ( only when we were moving slowly and I put it in neutral). Just a
single note from both until the prop stopped turning. The sound is a bit like
using a wet finger on a wine glass.
The cutlass bearings were replaced 12 years and 1500 hours running ago . We
thought we better have them looked at and we had the boat hauled out. The yard
pros said the bearings looked new. We had NO shimmy or vibration and have never
had any. We decided to ignore it and went on with the trip. The sound
disappeared shortly thereafter and was gone for the month's trip.
Now its back.
The only thing I can think of is- there must be some difference between fresh
water vrs salt water. We keep the boat in fresh water in Seattle and go through
locks into the saltwater of Puget Sound to vacation in our Northwest island
paradise. The sound came back within 2 running hours of being back in Lake
Union.
Having the boat kept in fresh water has lots of obvious advantages. One unusual
thing about our fresh water is that the lake water builds up a crust on zincs
which must be wire brushed off each year. (beats electrolysis and zinc
replacement every year). I am wondering if the fresh water is not as good a
lubricant for the cutlass bearings as salt water. Or there might be some lake
crust issue?
Has anyone ever heard of this bearing issue? I'd hate to change them if I don't
have to. Or should I change them as a matter of routine maintenance? I could
have it done next year when I haul out the boat. Can you do it cheaply or do
you have to pull the shafts as well?
I always value everyone opinions here. --
