I have not seen an OMC/BRP seal kit before and not sure if they supply a kit. I have limited experience with the Sierra kits, but they are economical, come with everything needed, and seem to work fine.
Individual OMC parts would be more expensive, which should mean better quality, but I’m not sure in this case.
The spaghetti seal can be bought in bulk from Grainger, McMaster-Carr, or a similar supplier very economically. It is sold as “Buna-N Oil-Resistant Rubber Cord Stock”.
