This is one of the Jacuzzi pumps. We took this at Nha Be before we moved out. The forward end of the pump is to your right. Down on the deck where you see those little notches, that's where she bolts to the intake plate. Remember when we looked up and saw those holes with those cutting slits in them, that feeds upward into the flat part here, and there were shims that we could put between the boat and the pump to get the height of this thing exactly the way we wanted, it to run and not leak onto the deck. On the top of it, it looks like a filler cap on a lawnmower or a gasoline engine. That's an inspection cap that served two purposes. You could lift it and look in there at the impeller without having to take the pump apart and also, you could clamp a fire hose to this top inspection port, bring the engine up to idle power on that side and you had a pretty good fire fighting capability if another boat was on fire or if a hooch or a hamlet had a fire, we could pull up there like firemen in rural America and help them put the fire out. And the locals, this is where we first developed some friendships along these rivers and canals, was our fire brigade. Now the far left part of the pump, the round part, that's the bowl is what it was called and the propeller, our impeller, blew the water into that bowl and then out through the nozzles. The far left part of that pump had a little piece that was called the “Bowl barring.” B-o-w-l barring. It was a brass part about the size of a twelve-ounce beer can. The impeller shaft was filled with a special grease called Alvania and then the barring was slipped over the impeller shaft. Early on, these bowl barrings didn't wear particularly well and the Alvania grease was hard to get and onboard YRBM-16 in our machine shop, our repair officer, warrant officer one, Bill Brigman and his guys could take bar stock and actually make a bowl bushing of their own and we never let that secret out to anybody, but Bill Brigman, again, if you're out there watching this, you were an honest to god mechanical genius as was your predecessor, chief warrant officer Matt McClure who was the repair officer when she was mined at Vinh Te. These were the guys that put her back together again.
