The PBT\/PET blend cap is stiffer and less prone to cracking from heat and vibration, helping the distributor retain alignment and sealing.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass resists corrosion for long service life.\u003c\/li\u003e\n  \u003cli\u003ePolymer cap resists warpage and thermal cracking.\u003c\/li\u003e\n  \u003cli\u003eStronger parts reduce chance of ignition misfires under load.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: Boat owners, marine technicians and DIY mechanics who maintain older MerCruiser-powered vessels with Delco HEI distributors will find this kit useful. It’s aimed at anyone seeking a direct-replacement rotor and cap that meets Mercury Marine specifications and offers improved resistance to corrosion, RFI and thermal stress typical in marine environments. Use it when restoring ignition reliability, performing routine distributor service, or preparing an older boat for a season on the water.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is this rotor and cap kit compatible with my 1995 MerCruiser V8?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
