Is this a genuine original part?

Yes, this is genuine Quicksilver Premium Gear Lube, manufactured by Mercury Marine to provide the highest level of protection for outboard engines.

How often should I change the gear lube?

Mercury recommends changing the gear lube at least once a year (typically at the end of the season before winter storage) or after every 100 hours of operation.

Can I use this in my 150HP Mercury engine?

No. This Premium Gear Lube is designed for outboards below 75HP. For 75HP and above, as well as all Mercruiser Sterndrives, we recommend using Quicksilver High-Performance Gear Lube (the blue/green formula).
