Every engine on my boat came due for an oil change all at the same time.
No problem, I have all the filters and oil in stock and a very nice oil changing set up.
I warmed up all the engines (all 4 - 2 mains, 1 generator, 1 outboard).
I hooked my oil extractor to the generator and started to extract. Nothing! My extractor is labeled so I can't accidentally hook it up backwards. I even checked it for suction before hooking it up. I rechecked it for suction, nothing.
Well, the oil extractor is 20 years old so must be the impeller. I pulled the cover plate off expecting the impeller to be missing its veins. The impeller looked just fine. I know the hoses can't be clogged; all they do is transport filtered oil.
Logic said it had to be the impeller despite its appearance. With out any other possible culprit I headed off to my nearest WasteMoney store for an impeller.
Sure enough, one quick impeller replacement and I was back to oil extraction. 10 gallons and 6 filters later I was done.
Now one side of my brain says buy a spare impeller. Fortunately, the logical side says not necessary as this failure will only occur in port.
