I have a deere 6068 in my lobster boat with two hydro pumps running off the pto. One runs the hauler and the other runs the steering. they share a 12 gallon tank. I was cruising in after a day of fishing and noticed my oil pressure gauge was hovering between 15 and 20 lbs when its normally at 35. I shut the engine down and pulled the cover off and the bilge was coated in oil. check the dipstick and the oil level was 3 inches above the full mark. disn't smell like antifreeze, so I check the hydro tank and there was only 6 gallons in it. So I think a seal let go in one of the hydro upmps and filled my engine with hydro oil. Boat gets hauled tomorow and the mechanic will start tearing stuff apart. I'd like to hear some opinions on what to do. engine has 8500 hrs. Boat didn't run hot, no smoking and no loss of power
