[Skools Out]

well no different when idling in the water if the hose is hooked up just run it with out the hood so you can feel all cylinders, head bolts, spark plug base's, t-stat housings, and heads on all cylinders not a bad idea to do so anyway on a start up on a sitting motor. that way you feel to be sure you have no hot spotting on the cylinders or any plug fouling issues, but rev it up once and a while with it in neutral. i kept my hands all over this motors heads and plug and sides of the cylinders for hot spots or a warmer cylinder, all stayed same temp and ran perfect.
