Hey Dan I checked in on the leak on the rotor gearbox on that 08 R-75 and it is leaking on the inside somewhere. I also checked in the book on what the gearbox holds and it said that it holds 5 pints so I put in 3 pints so there was some left in there. I was glad to see that there was a leak so I know that it just wasn't run low for like 300hrs. Going to get rotor out and figure out where leak is.
