FAQs

Q: Is this kit compatible with outboards that are not made by Mercury?

A: While designed for Mercury, the stabilizer, fogging oil, and grease are high-quality marine-grade products that can be used across most brands. For best results, stick with OEM for your engine.

Q: Do I need the larger sizes of stabilizer or grease?

A: Not necessarily. The 32 oz. stabilizer and 14 oz. grease cartridge are best for larger tanks or frequent service work. When it comes to single-outboard setups, smaller sizes often do the trick! They pack a punch while keeping things sleek and efficient.

Q: Is winterization really necessary if I only store my boat for a couple of months?

A: Yes. Even short storage periods can lead to stale fuel, internal corrosion, and seized fittings. A proper winterization routine ensures your engine is protected regardless of downtime.
