This COMP Cams camshaft is optimized for jet-boat bracket or performance use with A or B impellers, and includes a caution: it requires a melanized or nitrided distributor gear and is incompatible with untreated cast or steel gears. It’s aimed at higher-demand marine or racing settings where compatible hardware ensures durability and proper cam function under performance loads.
