    Question 951 (RXX want to be) cooling question..

    I've post some threads before about my headache jeje.. I have my Rx with twins and 91 mm bore .(still setting to get more millage) I was looking to a cooling system diagram for the RXX and notice that the lower cranckase has an extra cooling tray that my RX does not have . Mine is an 01 Seadoo . will that tray fit my crancase ? I switch to stock rejeted carbs (was using 50mm buckshots) and my compresion is about 150 psi per piston (stock head) (RXX mpem with no time curve corrected taking to the shop soon) Does my engine will suffer if this tray is not installed or there is another way to get my engine runn cooler .?

    I'm from Puerto Rico the temperatures here are about 92 degrees always
    Thanks for reading ..

    Don't bother with the case cooler, won't dramatically lower case temps, and you must pull the engine and tap the case hole for threads, not worth it and I've run a few both ways, back to back in testing.
