OMC Cobra hydrostatic seal rings?

[scrid55]

Hello everyone.
I recently tore into my 1991 OMC Cobra 4.3 lower gear case to replace a bent prop shaft. Upon disassembly I found the carrier bearing was moving so much it wore into the case slightly which I can build back up and machine down. However the hydrostatic seal rings are pretty much gone and I wanted to build up and re-machine those as well but I can't seem to find a good picture of what they are suppose to look like. My OMC manual picture of the rings is not detailed enough to make them out. Also wondering what the clearance should be between the hydrostatic seal rings and the prop flange when the prop is installed. Thanks if anyone can provide a close up image.

Are you talking about the two seals that press into the carrier after the needle bearing, items 27.
If so, they're not rings but rubber seals.

No, sorry I wasn't clear. Just on the inside lip of the lower unit gear case. Where the carrier housing slides in. Basically of you pull the prop they are machined in the inside lip of the gearcase just in front of the carrier housing. The book says they are to prevent excessive exhaust gasses from entering the prop area and causing cavitation.

Apparently they're not a replacement part. Maybe someone on here has the same drive and could take pictures and measurements.
If no one comes on here try starting a thread something like "need pictures of drive with prop removed".

Great idea thank you.
