Exhaust manifold-and-riser assembly (aluminium, e-coated for corrosion resistance), starboard side. Fits GM 5.7L (350 c.i.) V8. OEM on Indmar-powered inboards (MasterCraft, Supra, Moomba, Malibu, Nautique, ATX and others). Shares the GM small-block exhaust-port pattern of MerCruiser 5.0/5.7L, so it can cross-fit — but verify the riser angle and 3" exhaust-hose routing before ordering for a MerCruiser.
