"I had pulled my boat today to put her away for the 6 month winter here in Wisconsin. I have a 740B with a DP/C outdrive. When I winterize, I remove the 1 1/4" hose from the water pump, install an adapter I mad up and fun the engine on the hose until it heats up. I then drain the 4 petcocks to get most of the water out of the system and pull the thermostate. I have drains on the manifolds and 2 on the block itself. I always remove the "T" from the petcock and insert a pick to insure the passage is open. I than close them up and run 6 gallons of -100 antifreeze thru. However, today out of the port side block drain I got zero water out. I even turned the hose on, closed the other 3 drains, to try to get flowage thru this drain. Still nothing. I have had no over heating problems thru the season. I did the work at the ramp and not on level pavment. Would this have anything to do with it? Or do I have an internal blockage issue? Is there a way to clear it? Or am I just not realizing water should never came from there?"
