Suitable for single and dual outboard configurations up to 350 HP per engine.\u003c\/p\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eThis is the best-selling complete hydraulic steering kit for outboard applications and the right starting point for most single or dual outboard builds under 350 HP per engine. When a customer orders this kit, always confirm they also order the correct HO51xx hose set for their installation — hoses are not included and are the most commonly missed item. For dual-engine setups, add the appropriate tie bar kit to the order. For dual-station builds, a second helm, additional hose, and fittings will be needed. The adjustable O-ring fittings on both the helm and cylinder simplify installation and allow post-install reorientation, which is a strong selling point for DIY installers. Verify the engine has an ABYC standard tilt tube before confirming compatibility.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51199425708068,"sku":"1-HK64004","price":2617.29,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/1-HK64004.jpg?v=1785605230","url":"https:\/\/marisolmarine.com\/products\/dometic-hk64004-seastar-steering-kit-1-hk64004","provider":"Marisol Marine Company","version":"1.0","type":"link"}
