It uses a 3\/4‑16 thread, heavy-wall steel canister with epoxy corrosion protection, high-efficiency filter media, and an anti-drain-back valve that helps retain oil pressure between uses and reduces dry-start conditions on startup.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eThread: 3\/4‑16\u003c\/li\u003e\n\u003cli\u003eFilter type: 4-cycle outboard spin-on oil filter\u003c\/li\u003e\n\u003cli\u003eAnti-drain-back valve: Yes\u003c\/li\u003e\n\u003cli\u003eCanister: Heavy-wall epoxy-coated steel\u003c\/li\u003e\n\u003cli\u003eFilter media: High-efficiency, meets or exceeds OEM specification\u003c\/li\u003e\n\u003cli\u003eMarine-duty construction for freshwater and saltwater environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatible Applications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSuzuki DF115 4-stroke outboards, approximately 2002–2012 (verify by serial number)\u003c\/li\u003e\n\u003cli\u003eSuzuki DF140 4-stroke outboards, approximately 2002–2012 (verify by serial number)\u003c\/li\u003e\n\u003cli\u003eJohnson 90 HP 4-stroke outboards, selected 2003–2006 models\u003c\/li\u003e\n\u003cli\u003eJohnson 115 HP 4-stroke outboards, selected 2003–2006 models\u003c\/li\u003e\n\u003cli\u003eJohnson 140 HP 4-stroke EFI outboards, selected 2003–2006 models\u003c\/li\u003e\n\u003cli\u003eEvinrude 140 HP 4-stroke EFI outboards, selected 2003–2006 models\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eFitment Note:\u003c\/strong\u003e Sierra 18-7897 and \u003ca href=\"\/products\/sierra-18-7896-4-cycle-outboard-oil-filter\"\u003eSierra 18-7896\u003c\/a\u003e both cover Suzuki DF-series and Johnson\/Evinrude 4-stroke outboards, but serve different engine serial number ranges.
