      April 15, 2018 at 5:16 pm Purchased a 03 Sea Ray Sedan bridge with 500 hours on both engines. The manual says to adjust the valves at 500 hours.

Oil sample results came back high on both transmissions for Iron and Copper. Ā Both were about the same with Iron at 63 ppm and Copper 495ppm. Is this normal or to be expected? Signs of an issue?

      November 15, 2016 at 6:12 am A random oil sample on a properly operating gear, one with low hours, & one that has a visual oil inspection that looks clean & passes a “smell test” for anything burnt, is close to meaningless…………….Any experienced surveyor should know that, although in most cases rarely want to offer any opinions on the matter. Post some good pictures of the engines and the gear from all angles and perspectives.…
