Hello all. I am new to posting but have been reading advice for a while now so thanks to all the smart boat nuts on here. My problem is I am in the middle of rebuilding a 1987 DT140 and the new piston rings I got from browns have two different rings in the package, one green one blue, one stamper R and one RN. Can't find anything about the difference between the two and any help would be appreciated.

Thanks,
