We'd planned four days on the water last weekend with kids and grandkids. I spent 4 days getting the old tub ready, including washing, maintenance checks, replacing the AGM generator cranking battery and the 8-D engine cranking batteries, topping up and charging the 10 golf cart batteries. When I fired up the big CATs to check them out, the port engine had no cooling water coming out the exhaust port. Nothing new, and something many of us have experienced on an engine or generator sea water pump.
Since I'd previously had all raw water hoses replaced, I realized that the 'dry' hoses didn't allow the water pump to achieve prime, and that the impeller had been fried. I had a spare impeller on board, but I can't get to that pump. I tried several local and not-so-local mechanics, but it was a holiday weekend, and they were either backed up or had their own plans for the weekend. In a desperate move, Chris squeezed in there, but didn't have the strength to break the bolts loose.
So, the grandkids spent the weekend afloat in our back yard.
Today, one of the guys rang my doorbell. Two hours later he had the spare impeller installed and had tried to find any 'loose' bits of the old impeller that were in hoses between the oil cooler, raw water pump, and aftercooler.
I brought the old impeller up to the house for Chris to put the pieces of the jigsaw together. Attached are a couple of pictures of old, new, and pieces of impeller.
For calibration, the 'good' impeller is approx 3.5" diameter and 4" long.
