Re: FICHT EVINRUDE 1998 175 H P
There are some good '98 Fichts out there. If the upgrades have been installed and the plugs are properly indexed, do the regular maintenance and they should be fine.<br />Run a good brand-name 87-89 oct fuel, and in my opinion, the Bombardier XD-50 oil, or the earlier version (FICHT RAM) would be the only 2 oils I would consider. Change the sparkplugs every year, and the waterpump every-other year.<br />Do a decarb every year and fog them if not going to be in use for more than 30-45 days.<br /><br />EDIT: I would also recommend an OEM manual so you understand the standard maintenance intervals and how to index the sparkplugs.
