Cometic H3022SP5030S Sea-Doo 4-Tec MLS Head Gasket 100mm Bore .030" Thickness

The Cometic H3022SP5030S is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered for Sea-Doo 4-Tec 1503cc and compatible ACE 1630cc engines. With a 100mm bore and 0.030" (0.762mm) compressed thickness, this gasket delivers a reliable, high-performance combustion seal capable of withstanding the extreme pressures of today's high-output personal watercraft engines.

Key Features:

• Multi-Layer Steel (MLS) construction — comprised of multiple embossed stainless steel layers for superior strength and rebound characteristics
• Viton (fluoroelastomer) outer coating on both sides creates a micro-seal against the head and block surface, preventing fluid intrusion
• 100mm bore diameter with 0.030" compressed thickness
• No sealants required — MLS design provides maximum sealing performance straight out of the box
• Corrosion resistant stainless steel construction resists fuels, coolants, and oils
• Ideal for aluminum head to aluminum block applications, withstanding the shearing forces created by dissimilar materials
• Designed for high-output, high-RPM performance builds (compatible with 8400+ RPM tunes)
• Works with stock intercooler location and is compatible with stock or aftermarket exhaust systems

The Cometic H3022SP5030S is a direct-fit replacement or performance upgrade head gasket for Sea-Doo 4-Tec powered personal watercraft. Whether used in a stock rebuild or a high-performance engine build, this MLS gasket provides the sealing integrity demanded by today's forced-induction and naturally aspirated PWC powerplants.
