This is a motor-only replacement — not a complete pump, reservoir, or bracket assembly — making it the right repair option when the existing hydraulic components are still serviceable and only the electric motor has failed. Ring-terminal wire ends match the original electrical connection on compatible Oildyne-equipped applications.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e12-volt replacement tilt and trim motor — motor only, not a complete pump assembly\u003c\/li\u003e\n\u003cli\u003eDesigned for Oildyne-style hydraulic trim pumps on MerCruiser I\/O and Mercury outboard applications\u003c\/li\u003e\n\u003cli\u003eRing-terminal wire ends for direct connection to original wiring\u003c\/li\u003e\n\u003cli\u003eReplaces multiple Mercury \/ MerCruiser OEM trim motor part numbers\u003c\/li\u003e\n\u003cli\u003eARCO Part Number: 6218 | SKU: 57-6218\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eReplaces \/ Cross-References\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMercury \/ MerCruiser 17649\u003c\/li\u003e\n\u003cli\u003eMercury \/ MerCruiser 17649A1\u003c\/li\u003e\n\u003cli\u003eMercury \/ MerCruiser 17649A02\u003c\/li\u003e\n\u003cli\u003eMercury \/ MerCruiser 17649T\u003c\/li\u003e\n\u003cli\u003eMercury \/ MerCruiser 87828\u003c\/li\u003e\n\u003cli\u003eMercury \/ MerCruiser 891736T\u003c\/li\u003e\n\u003cli\u003eSierra 18-6772\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMerCruiser sterndrive (I\/O) applications with Oildyne hydraulic trim pump and 12-volt motor\u003c\/li\u003e\n\u003cli\u003eMercury outboards with Oildyne trim pump and 12-volt ring-terminal motor configuration\u003c\/li\u003e\n\u003cli\u003eVerify using the engine or drive serial number, Oildyne pump style, 12-volt system, ring-terminal connection, and original motor part number before ordering — similar-looking trim motors may not interchange\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eBest Use Case:\u003c\/strong\u003e The 6218 is the right repair choice when electrical testing confirms the trim motor has failed but the Oildyne hydraulic pump, reservoir, and valve body are still in serviceable condition — replacing the motor only is more cost-effective than swapping the complete assembly. Common failure indicators include intermittent trim operation, excessive corrosion on the motor, damaged electrical leads, or a motor that no longer runs reliably under load. The critical fitment check is the Oildyne pump with 12-volt ring-terminal motor configuration — match the original Mercury\/MerCruiser part number before ordering.
