Product: Wear Ring Replacement for Spark Ace 900 / Spark 900 HO ACE / Spark Trixx Reference part numbers: 267000617, 267000813 Key benefits Restores impeller clearance to factory specification, recovering lost pump efficiency and thrust. Reduces cavitation and flow disruption that cause noise, vibration, and performance loss. Durable, wear-resistant construction extends service life and reduces frequency of repairs. What it does Function: replaces worn wear ring to restore tight play of the impeller, compensating for performance loss caused by ring wear and reducing cavitation. Material: made from high-strength ABS for improved wear resistance and long-term durability in marine environments. Fit: intended as a replacement for Spark Ace 900, Spark 900 HO ACE, Spark Trixx models (reference part numbers 267000617 and 267000813). Why you need it Worn wear rings allow excessive impeller clearance, lowering pump pressure and reducing thrust. Replacing the ring restores correct clearances and performance. Prevents progressive damage: reduced cavitation and better sealing protect the impeller and housing from accelerated wear. Increases reliability during heavy use or in abrasive conditions thanks to the high-strength ABS construction. Performance and durability Wear-resistant ABS provides consistent dimensional stability and reliable service life under normal marine operating conditions. Maintains pump efficiency and minimizes friction-related hull or component damage in harsh sea conditions. Typical applications Routine maintenance: replace the wear ring during scheduled inspections to restore pump performance and avoid downstream damage. Post-wear repair: install after detecting cavitation, increased vibration, or noticeable loss of thrust from the jet pump. Seasonal prep: fit before a season of heavy use or after winter storage to ensure optimum pump clearance and performance. Compatibility and installation notes Designed as a direct replacement for Spark Ace 900, Spark 900 HO ACE, Spark Trixx and compatible models. Check reference part numbers 267000617 and 267000813 to confirm fit. Installation should follow manufacturer torque and clearance specifications; inspect impeller and housing for related wear when replacing the ring. Reliable, service-oriented replacement that restores impeller clearance, reduces cavitation, and extends jet pump life for Spark Ace 900, Spark 900 HO ACE, Spark Trixx models (ref. 267000617, 267000813).
