Hey guys, I have twin 2005 4.3s. Upon start up, both have about 55 psi oil pressure. After about 15 minutes cruising at 3500, port oil pressure drops to about 35. At idle, it will drop to about 20. Starboard will stay at 55 and drop to 30 at idle. Any ideas as to what would cause the drop in pressure on the one motor? On changing the oil, the oil does seem lighter in color, but can find no evidence of water in oil. Oil level remains the same. Might use a quart of oil over the season. This has been going on for about 2 years now. I will change the sensor. Is there one sensor for both smart craft and analog gauges? What would be your next step? Thanks guys. Tony
