2000 DP-SM gear oil substitute?

[ChrisCraftFan]

I am sure this has probably been beaten to death but I could not find it. Does anyone use gear oil other than the Volvo Penta 75w90 in their out drive? I am going to change it for good measure but that gear oil has gone up about $12 a quart since last June. I got it for just under $16 a quart last June and its about $27 or $28 now. Not worth risking damage but if there is a better solution that I may even be able to pick up locally I would do it.

I run 75-90 from the local parts store (full synthetic) but I also change it every year regardless of hours,8yrs like this so far and no problems

If you can find 75w90 that doesn't have a friction modifier in it...good luck. I just use the Volvo fluid. It isn't much more than what the auto parts store carries. Buy it by the gallon on iBoats

$30.99 a quart on iBoats. The no friction modify question is what i am hoping some that is already doing it can help me with.

Anyone use this stuff? [h=1]Mobil Delvac Synthetic Gear Oil 12203[/h]
It seems to have no limited slip additives. About $35 a gallon

I like the amsoil choice so far if you join for $10 you get them for $10.10 a quart! I have always likes Amsoil products

Starting to chicken out - read a couple things about the cone clutch not being happy with other lubes

Been using Amsoil for nearly 10 years in a 290DP

It does fine with cone clutches
