Questions & Answers
Is this a genuine original part?
Yes, this is an authentic Quicksilver product, which is the official parts and lubricants brand for Mercury Marine / MerCruiser.
How do I know if it is compatible?
This "High Performance" formula is mandated for all MerCruiser sterndrives and Mercury outboards 75HP and above. Check your owner's manual to verify the viscosity requirement.
Can I mix this with standard Premium Gear Lube?
No. It is strongly recommended not to mix Quicksilver High Performance Gear Lube with standard Quicksilver Premium Gear Lube (the bottle with the green label), as the additive packages are different and mixing can reduce performance.
Note: Proper maintenance requires changing gear lube once per year or every 100 hours of operation. Visit 4boats.co.uk for gear pumps and additional maintenance kits.
