Ayuh,....

I think it calls for Merc Hi-Performance syn-oil Gear Oil....

I use Mobil 1, in 75W-90 in Mine.....

What year and what type of 5.7 Mercruiser outdrive do you have?

Re: alpha one drive oil

The outdrive is a raw water cooled alpha one. I am not too happy with the raw water cooled, we purchased the boat from some friends this year for 5k! The boat is a 24ft chaparrel, the motor just had 3k worth of work done to it last year, I was not able to get a receipt from the owner!

The only oil recommended by Mercury is Quicksilver High-Performance Gear Oil.....

High torque engine in a heavy boat.... You want all the protection you can get....
