YAMAHA FX-SHO/SVHO/FZ • INTERCOOLER • COOLING ENGINE BLOCK THERMOSTAT KIT COOLING OPTION The R&D Block Thermostat Kit Option was developed to offer a way to run “Dual Thermostats” to the engines cooling system to control and allow warm up and pre heat cycles to take place. Engine Block and Head cooling on the Yamaha Engine becomes difficult when running high compression ratios, higher boost levels, and aggressively advanced ignition timing. R&D has found that multiple cooling lines need to be added to the cooling system to provide enough volume to keep temperatures stable and in check. The problem is the Single OEM thermostat is too restrictive and doesn’t allow enough water volume flow to reduce temperatures with the added cooling lines. R&D has found a way to add an additional thermostat that allows enough water flow volume to cool the engine and head and retain the OEM method for engine pre heat or warm up. The R&D Kit installs as a bolt on kit directly in place of the corrosion anode. Running two thermostats allows enough water flow to cool the engine properly. The R&D thermostat kit option will start to open at 120 degrees, and will allow full flow at 140 degrees. The OEM stock thermostat opens at 118-126 degrees and allows full flow at 140 degrees. Having two thermostats installed that are full open at 140 degrees, and flow enough water volume, will help to keep engine block temperatures to between an ideal 150-175 degrees. R&D has done extensive testing with the engineers at MoTeC both on the Dyno and on the water to determine that 150-160 degrees block temperatures is where the most peak power is, any hotter and power diminishes. The R&D dual thermostat kit will be a must have addition where engines are being run in extreme cold water and weather conditions.

For 2015, this event is a two-round tour which begins with the very popular Mark Hahn 300 on February 28. Competitors who opt to join the World Endurance Tour will have their watercraft transported from Lake Havasu City to the second round in Vladivostok, Russia. Once in Vladivostock, there will be an intense final round that lasts from August 11-16. For the inaugural season, there will be two competition cate- gories: Pro/Am Runabout Open and Runabout Stock. Entry fees are $2,200 per team (in addition to Mark Hahn 300 fees). Each entry includes the following: • Round trip shipping of a PWC from Lake Havasu City to Vladivostock, Russia and back to Lake Havasu City • One hotel room, including breakfast.
