"I have an oil leak in the upp
"I have an oil leak in the upper gear housing and am getting ready to replace the o-rings and oil seal. But my question is this, what kind of sterndrive lubricant does a Volvo 270 outdrive use? I ask because the leaking oil sure smells like 90 weight gearcase oil.
On marinemechanic.com I found the following statement "270/280/290 Volvo sterndrives DO NOT always use 30 w engine oil for lubricant." So now I am concerned.
Did the VP 270 ever use 90 weight gearcase oil as a lubricant?
I last had it serviced at a marine shop before moving in 2004, with little use since. If someone did put 90W gearcase oil in there would it have caused any damage? What effect would it have? If I drain it to change the oil seal and then refill it with 10W30 will that now cause any damage?
Any help will be appreciated."
