Does anyone have experience with an anti-slip additive for marine
transmissions? We have a Hurth HBW-150 R2 transmission that is
slipping, and we may have to alter our cruising plans as a result.. I
really don't want to continue without a workable transmission as I've
seen too many situations where sail alone was inadvisable, especially
in some of the Bahama cuts..

We changed the fluid, checked the linkage, and have been babying it
since first noticed.. It doesn't have an oil cooler, and I'm aware
that might help, but what we have is what we have..

Anyone with suggestions?
