Am in the process of buying a 2006 34 PC with V-drives and 8.1 HO Mercruiser engines. The oil analysis for the starboard gear came back with abnormal 28 PPM of chromium and 421 PPM of iron. The port gear results were all normal and there are about 570 hours on the engines. ZF 63-IV transmission. The boat was VERY lightly used the last 2-3 years due to a foreign owner who could not get here from Europe. I am looking for help in judging whether this is an immediate and fix it now issue or one that can wait a bit. Thanks for any help.
