I've been told two different methods to winterize my boat. The first is to drain the block and manifolds, then pour the pink stuff down 3 of the 4 hoses at the t-stat. The 4th will just run out the back. The second is to drain the block and manifolds and use the hose and bucket method to suck the pink stuff up through the out drive and into the engine. Which one is best and why?
