Looking at a GB with older (1974) twin Lehman 120s and have a couple questions about oil pressure. Both engines are around 3000 +/- hours. The boat consistently runs about 30+ psi on the starboard engine, 20+ on the port side. (Gauges are inaccurate, these readings are taken at the engines by an experienced mechanical surveyor.) We have oil analyses that show nothing unusual from 5 years ago and 6 months ago and expect a current report this week (although for the current sample, only have 10-15 approx hours since oil change.) We don't expect the new analysis to show any changes. Current owner says boat isn't using oil and we have no reason to doubt that assertion. Engines run well, no knocking or pinging, no scary smoke or sheen, etc. I'd really appreciate thoughts from those of you more experienced than we are -- would you be confident, cautious or run?
