The number indicates horsepower (110). Suffix letters denote shaft length (S = 15\", L = 20\", X = 25\", U = 30\") and control type (R = Remote, H = Tiller). A final letter often encodes the model year.\u003c\/li\u003e\n    \u003cli\u003e4‑Stroke confirmation: Four‑stroke models start with “F”. If yours does not, recheck because parts differ from 2‑stroke platforms.\u003c\/li\u003e\n    \u003cli\u003eShaft and controls matter: Measure from the transom bracket to the anti‑ventilation plate to confirm shaft length, and note whether you have remote or tiller controls—both affect parts such as propellers, rigging, and anodes.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/section\u003e\n\n\u003csection id=\"engine-overview\" style=\"max-width:900px;margin:0 auto;padding:12px;\"\u003e\n  \u003ch2\u003eEngine Overview\u003c\/h2\u003e\n  \u003ch3\u003eInline‑4 EFI Four‑Stroke (110 HP class)\u003c\/h3\u003e\n  \u003ctable style=\"width:100%;border-collapse:collapse;\"\u003e\n    \u003cthead\u003e\n      \u003ctr\u003e\n        \u003cth style=\"text-align:left;border-bottom:1px solid #ddd;padding:8px;\"\u003eFeature\u003c\/th\u003e\n        \u003cth style=\"text-align:left;border-bottom:1px solid #ddd;padding:8px;\"\u003eDescription\u003c\/th\u003e\n      \u003c\/tr\u003e\n    \u003c\/thead\u003e\n    \u003ctbody\u003e\n      \u003ctr\u003e\n        \u003ctd style=\"padding:8px;border-bottom:1px solid #eee;\"\u003eConfiguration\u003c\/td\u003e\n        \u003ctd style=\"padding:8px;border-bottom:1px solid #eee;\"\u003eInline‑4 four‑stroke with electronic fuel injection (EFI); 12‑valve or 16‑valve architecture depending on variant\u003c\/td\u003e\n      \u003c\/tr\u003e\n      \u003ctr\u003e\n        \u003ctd style=\"padding:8px;border-bottom:1px solid #eee;\"\u003eCommon Models\u003c\/td\u003e\n        \u003ctd style=\"padding:8px;border-bottom:1px solid #eee;\"\u003eYamaha 110HP four‑stroke outboard models (verify exact model code and suffix for parts fitment)\u003c\/td\u003e\n      \u003c\/tr\u003e\n      \u003ctr\u003e\n        \u003ctd style=\"padding:8px;border-bottom:1px solid #eee;\"\u003eAdvantages\u003c\/td\u003e\n        \u003ctd style=\"padding:8px;border-bottom:1px solid #eee;\"\u003eQuiet operation, good fuel economy, broad mid‑range torque, and dependable charging output for electronics\u003c\/td\u003e\n      \u003c\/tr\u003e\n      \u003ctr\u003e\n        \u003ctd style=\"padding:8px;border-bottom:1px solid #eee;\"\u003eNotes\u003c\/td\u003e\n        \u003ctd style=\"padding:8px;border-bottom:1px solid #eee;\"\u003eMany service parts overlap with the 100–115 HP family.
