On older AQ, SP, and DP setups, replacing a worn hose connection during cooling-system service can help prevent repeat leaks and save time when the drive or hose routing is already apart. The main key is matching by serial number and layout, because several closely related Volvo Penta numbers are commonly grouped together in replacement catalogs.\u003c\/p\u003e\n\u003cp\u003eShipping: Ships same or next day for fast Canada wide shipping. ⚓\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43564047368228,"sku":"851766","price":90.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/6acf0779-d7f3-4b13-85ad-1c5ee51e4861.png?v=1776192041","url":"https:\/\/marisolmarine.com\/products\/volvo-penta-851766-hose-connection","provider":"Marisol Marine Company","version":"1.0","type":"link"}
