outdrive oil question

[ron3033]

I have a 1995 Four Winns with a Volvo Penta SX Cobra outdrive (light gray colour) plate on side of outdrive says product number 3868156 type (left blank) gear ratio1.66 I believe it is a cone clutch.

I always used OMC Ultra HPF gearcase lube PN508318, yellow oil, but got discontinued. I now have been using Bombardier Evinrude/Johnson Ultra HPF gearcase lube PN 775601. But it seems this is not around now either, or I just have not found some. I was told Evinrude/Johnson Ultra HPF Pro is different?

Is Mobil 1 GL 5 standards, 75w90 okay for this drive? Supposedly, Mobil makes the Volvo Penta oil, but it is $20 +++ a litre.

I can't post a picture of the Bombardier oil for you.
Thanks

You can use whatever you want if it meets specs. Supertech 75w-90 will work as well as any. I worked on many Volvo/Pentas in the Coast Guard. Did we use Evinrude, Johnson, etc? Nope. Bulk automotive gear oil and they saw some severe duty.

Walmart carries a lot of marine oils & gear oil where I live. I would assume you can use a 75W90 marine gear oil. The marine gear oil can handle any water that gets in better than normal gear oil. Most marine gear oils are very similar except for the one designed for the Evinrude electric shift.
