My opinion of fishermen as a race has taken a dive in the last week or so. I'm in the process of stripping a big (31 litre) Kelvin diesel, from a fishing boat, which has a seized crankshaft. My understanding is that it was rebuilt by Kelvins 8 or 9 years ago at a cost of £30K+. It's pretty obvious that it had simply been run out of oil. The sump takes 77 litres, I pumped less than 25 litres out of it, there's no evidence of major oil leaks. I'm told that that standard of maintenance is not uncommon :-(
