Doing an engine rebuild or just need to replace some stripped or worn bolts on your Sea-Doo? This complete bolt kit has you covered. It includes all the essential engine bolts for the popular 4-Tec 1503 and 1630 engines found in Sea-Doo personal watercraft and boats from 2002 all the way up to 2022. The kit is packed with: 8 cylinder head bolts (part # 290641110 / 420641110, size 11x147mm), 8 crankcase bolts (# 290641120 / 420641120, 10x82mm), 6 rocker arm bolts (# 711641080 / 420641080, 8x72mm), and 6 connecting rod bolts (# 420640990 / 420640991). These are direct OE aftermarket replacements, meaning they're made to the same specs as the original bolts for a perfect fit and proper torque. Using a matched set ensures even clamping force and reliability. Whether you're a DIY mechanic or a professional shop, having all the critical fasteners in one kit saves time and hassle compared to sourcing them individually. Always follow proper torque sequences and specifications during assembly. A must-have for any serious 4-Tec engine repair or overhaul project.
