I have a 1992 AQ131 engine with a Volvo SP CD Trim outdrive. The s/n numbers are FA 393 11 and 854891. A while back Don advised me to run engine oil in the drive, which others have also recommended. I looked at a posting that Don did with VP outdrive info yesterday, and for my drive, which I have been told is the 290, it recommends gear oil, I believe 90 wt. Would like to know which one is correct, now I am just running engine oil in the outdrive.
Thanx for your help and have a great day,
Rob.
