I met Mr. Martin Ball, a mechanic out of Long Beach, who's an independent operator. He came aboard, we chatted for a few minutes and he gave me an estimate of the costs. (We'll keep that part to ourselves). I told him to go ahead and proceeded to watch a Master Mechanic at work. He looked at the engine and gave me his opinion of its condition, (as far as it just standing there without being started). He then, quickly removed and disassembled the impeller pump. The impeller wheel was missing one of its fins.
The impeller pump unit itself was not in the best of condition, but he suggested we try to clean it off and use it and see how it goes. More on that later... I showed him the impeller that the PO left for me along with the gasket. Unfortunately, the current impeller pump uses a rubber ring, not a paper gasket. And, the impeller itself is of a different design. Martin had one with him...so the other one is headed for ebay.
The exhaust elbow was totally clogged with gunk. It required a weld to the new one...so Martin drove back to Long Beach and got that done.
After re-assembling everything the exchanger, he gave me a lesson on how to put the impeller pump back on. We started up the engine and I was never so happy to see water spurting out of something before in my life. (What a goofball!)
Unfortunately, and Martin had warned me about this, the impeller pump has a very slight leak. Martin suggested running the engine under load for a while and see if the seal doesn't take. It didnt, so Martin is giving me the name of his rebuilder and I will drive to long beach and give it to them for a couple days, then reinstall. To be safe, I made sure the seacock was off before I left the boat. I havent received the bill yet, but I learned a lot and I met a good mechanic whom I can trust.
