If your engine specifies OEM belt 914787 or 3858462, this is the correct replacement. It is also a practical onboard spare — belt failure on these drives can take out steering assist, raw water cooling, and charging simultaneously.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon Issues:\u003c\/strong\u003e The most frequent ordering error is selecting by belt length alone without verifying the OEM part number. Several belts of similar length were used across OMC and Volvo Penta power-steering and alternator positions — always cross-reference against 914787 or 3858462 to confirm the correct belt before installation.\u003c\/p\u003e\n\n\u003ch2\u003eRelated Parts\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/marisolmarine.com\/products\/sierra-marine-v-belt-18-15440\"\u003eSierra Marine V-Belt 18-15440 — 44 in. \/ 111.8 cm\u003c\/a\u003e — shorter belt in the same cogged series\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/marisolmarine.com\/products\/sierra-v-belt-47-15455\"\u003eSierra V-Belt 47-15455 — 44.5 in.\u003c\/a\u003e — intermediate size\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/marisolmarine.com\/products\/sierra-marine-v-belt-18-15470\"\u003eSierra Marine V-Belt 18-15470 — 47 in. \/ 119.4 cm\u003c\/a\u003e — next size up in the same series\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/marisolmarine.com\/products\/sierra-marine-v-belt-18-15480\"\u003eSierra Marine V-Belt 18-15480 — 48 in. \/ 121.9 cm\u003c\/a\u003e — 48-inch variant\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/marisolmarine.com\/products\/sierra-marine-power-steering-v-belt-18-15520\"\u003eSierra Marine Power Steering V-Belt 18-15520 — 52 in. \/ 132.1 cm\u003c\/a\u003e — longer power-steering belt in the same family\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c\/section\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51037541105700,"sku":"47-15450","price":54.39,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/47-15128_3856b7a4-6886-4f90-babc-67b163679a91.jpg?v=1783568589","url":"https:\/\/marisolmarine.com\/products\/sierra-marine-power-steering-v-belt-18-15450","provider":"Marisol Marine Company","version":"1.0","type":"link"}
