The R&D Yamaha 1.8L Recreational Engine Cooling Kits were developed for recreational and offshore racing use. Extensive engine cooling temperature testing and digital data logging has proven the R&D Cooling Kits to offer increased water volume flow through the engine, oil cooler, and intercooler as well as increased water pressure. The O.E.M. Yamaha cooling system has a very low water pressure (10 P.S.I. at 7600 rpms) and a low water volume flow. The new R&D single line addition kit will lower engine block and intake air temperature by 15-20 degrees. Kit comes complete with pictorial instructions. The kit works on all 2008+ year model Wave Runners with the 1.8L supercharged or naturally aspirated engine. It is now available from R&D with Pt. # 660-18006 at the cost of $99.95.
