“I will not sleep on this boat. I’m going home–NOW!” said my overheated sailing mate and spouse, Monica.  
My brother was hanging upside down, peering through a 9-inch square cutout in a bulkhead at the raw-water pump housing on his 3-cylinder Yanmar marine diesel. “How the heck do you get the impeller out of there?” he asked me.This is a very good question.
