The synthetic base stock delivers better film strength and thermal stability than conventional mineral oils, while the blend pricing keeps it accessible for regular service intervals. This is a gallon jug — the right size for shops, multi-boat owners, or anyone who services their lower unit more than once a season.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSynthetic blend formulation\u003c\/strong\u003e — better long-term protection than conventional gear oils, at a lower cost than full synthetic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSAE 80W90 viscosity\u003c\/strong\u003e — correct weight for most outboard and sterndrive lower units\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtreme pressure (EP) and anti-wear additives\u003c\/strong\u003e — protects gears and bearings under high load\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRust and corrosion protection\u003c\/strong\u003e — guards internal components in the wet, salt-exposed lower unit environment\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExcellent thermal stability\u003c\/strong\u003e — maintains viscosity across a wide operating temperature range\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended for engines over 100 HP\u003c\/strong\u003e — where gear loading is higher and oil quality matters more\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications \u0026amp; Certifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eViscosity: SAE 80W90\u003c\/li\u003e\n\u003cli\u003eAPI service: GL-5, MT-1\u003c\/li\u003e\n\u003cli\u003eMeets: SAE J2360, Mack GO-J\u003c\/li\u003e\n\u003cli\u003eSize: 1 US gallon (3.78 L)\u003c\/li\u003e\n\u003cli\u003ePart number: 27200\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eBest use case:\u003c\/strong\u003e This gallon format is the practical choice for outboard service shops, marina technicians, and multi-boat owners who go through gear lube regularly and want the cost-per-litre advantage of buying in bulk. It’s particularly well-suited for high-horsepower outboards (100 HP+) and performance sterndrives where the EP additive package makes a meaningful difference in gear protection.
