Grease fitting 76 OMC 175

While greasing everything today I got to the exhaust housing plug, plug broke apart and it looks like the grease fitting is missing. Can I put a generic fitting in there or do I have to use the exact part number?

Generic is fine, OMC never made grease fittings

Thank you much! Any idea how I figure out the size? I found the part #313607.

Measure the diameter of the hole, then find one that meets same

The thread pitch is 1/4”X 28 for Zerk fittings. Do not worry about replacing the red plastic plug or trying to find a new one. 400-800 drives just have a un threaded hole in the same place.
