Gimble brg seal or no seal?

[grewvin1]

305V8, Alpha out drive, removed bad gimble brg and seal. Purchased new brg but cannot find seal in stock most marinas explain they don't put them in anymore. True?

True, all it does is keep the grease from going inside,usually not a problem if you service in properly.

Do you now have the new perma‑lube gimbal bearing kit?

MerCruiser transom assemblies are now equipped with a sealed, permanently lubricated (perma‑lube) gimbal bearing that does
not require maintenance lubrication. Current production transoms use the perma‑lube gimbal bearing and do not require the grease
fitting on the gimbal housing or the grease retention seal in front of the gimbal bearing. The specified perma‑lube gimbal bearing
is the replacement gimbal bearing type for all transoms. Replacement perma‑lube gimbal bearings come with a special plug to
replace the grease fitting. When replacing a lube‑style gimbal bearing with a perma‑lube bearing, it is necessary to remove the
grease fitting from the transom and install the special plug.

Transom assemblies with perma‑lube gimbal bearings do not require a grease retention seal in front of the gimbal bearing.
However, when installing a new perma‑lube bearing, it is not necessary to remove the seal from transoms that have the seal
installed.

What FunTimes post means is that the seal is not really needed if you are using the Perma-lube bearings, but if you have a bearing with the grease hole in it, you need that seal. It is there to keep dirt out, not water from coming in or grease from getting out.
You might check with your local NAPA store, they carry Sierra parts and may have the 18-2094 seal you need.
