Some of you have inquired about my petcock drain I installed to make winterization much easier. With this setup you can drain the block in about 3 minutes, which includes opening and closing the petcock valve.
I picked up the parts at a local Marine store, unfortunately I cant remember what size thread it is. Easy way to do this is to take off the knock sensor, remove the plug and take it with you to match up the threads. The picture should show you all the parts you need. Make sure and use teflon tape on all threads to prevent any leakage. It has worked great for the last couple years with no problems.
The picture I posted is the side I ran my hot water shower line off of, this denotes the red line coming off the cross connector. The only thing you MUST do is keep the knock sensor in-line with the block. DO NOT run it off the side of the T or cross or else your motor will start running poorly.
Hope this helps, if you have any questions please ask!
