I posted a while ago about my 4.3 w/omc stearn drive over heating. After buying the SELOC Manual for it I discovered that the drive is the SX model and I cannot find the impeller. There is no place in the manual about the cooling system of the SX, just the upper gear housing which is completly different from the regular OMC drive. I have a good notion that the impeller is bad and need to locate it. <br /><br />Thanks for any help in advance!!<br /><br />Dan
