The R&D 5 Port Extra Cooling Manifold is a bolt on part that replaces the OEM cooling manifold mounted to the top of the jet pump. For offshore and high performance use where engine loads are sustained for longer distances, R&D recommends adding extra cooling to the engine, oil cooler, and intercooler. The R&D manifold provides 3 additional ports over the stock manifold. CNC machined from billet aluminum, o-ringed sealed and anodized for corrosion resistance. Kit comes complete with five ½ fittings. Additional ½ to ½ through-hull water fittings (R&D Pt. # 660-00012) required for each additional line, order as needed. Pt# 660-82501 Now Available at Retail $119.95
