No ideas on the bearing differences?

I don't know for sure but probably just a different supplier, new ones look like the one with circles on the sides not the raised areas... A more solid cage edge may retain oil better..Dave

Any difference in roller size. I measured between Merc and ProMarine on rod roller and Merc was smaller. Shorter - .0165

Thanks, FMP!
I’m on vacation on the Canary Islands, but I will check this when I get home to Sweden and post the result!

The hunt for details prior reassembly continues...
About the connecting rods; is it a good idea to polish the rod journals before reassembly? Like a slight hone creating som small scratches for the oil to stick to?
A slight rub by hand with 400 wet paper?
Greatful for your opinions and advice!

Yes, I always do anyway. I use a little 400 grit ball hone. By hand is fine too, just try to make cross hatches when doing it. Great thread btw.

No , different applications, Merc part vs Pro Marine . Metal cages ,old x flow but the difference surprised me , made it note worthy. A bit extra running surface may help.
