The complete reservoir bottle is a separate assembly (8M0075708, 8M0075709, or 8M0075710 depending on application). Order the appropriate bottle assembly if the reservoir itself is cracked or damaged.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the gear-lube monitor system?\u003c\/strong\u003e\u003cbr\u003eA: It is a passive visual monitoring system that connects the sterndrive gearcase to a small reservoir in the engine compartment via a hose. The reservoir level allows quick visual confirmation of gearcase lube status. A drop in reservoir level can indicate a gearcase seal leak that should be investigated.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does 8067271 fit both Alpha and Bravo drives?\u003c\/strong\u003e\u003cbr\u003eA: Yes, Mercury confirms fitment across Alpha and Bravo sterndrive applications where the gear-lube monitor reservoir is installed. Confirm the reservoir bottle style before ordering, as different bottle assemblies were used across production ranges.\u003c\/p\u003e\n\n\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eBest use case:\u003c\/strong\u003e Order 8067271 when the reservoir cap is damaged, missing, or no longer sealing on a MerCruiser Alpha or Bravo sterndrive with a gear-lube monitor system. It is most commonly needed after a drive service where the cap was cracked or lost.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon issues:\u003c\/strong\u003e The most frequent confusion is customers ordering this cap when they actually need the complete reservoir bottle assembly — the cap is inexpensive and easy to overlook as a separate part. If the reservoir bottle itself is cracked or leaking, the correct part is one of the 8M0075708 \/ 8M0075709 \/ 8M0075710 bottle assemblies, not this cap. Also confirm the reservoir is the style that uses this cap before ordering, as Mercury used different monitor configurations across production years.\u003c\/p\u003e","brand":"MERC","offers":[{"title":"Default Title","offer_id":43563878580260,"sku":"8067271","price":22.07,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/e69feff5-adf7-47b5-a47e-0f09177d1fe5.png?v=1788662487","url":"https:\/\/marisolmarine.com\/products\/merc-587","provider":"Marisol Marine Company","version":"1.0","type":"link"}
