How many man hours..?
Posted: Wed Jun 06, 2007 1:15 pm
I recently purchased a Silver Century. I didn't pay too much for it, there was no opportunity to see it running nor even to see if it had a spark. It was clean enough, all the bits were there and it had lots of compression.
When I got it home it naturally found its way to the test tank and after a quick swill through of the fuel system I was pleased to discover it started on the second pull, and revved freely.
No water, however. Not a problem, I thought. Whip the block off and dig the muck out.
I managed to shear three of the cylinder head studs, and only managed to extract two of those, so a fair amount of time and patience was expended on that one stud. I also managed to shear off the brass water pipe union - more time.
I thought I'd replace the HT lead while I was at it, and managed to wind the small stud off the baseplate flush with the surface. I have to say I've never had a motor that was so awkward in terms of reasonable looking fasteners that proved to be a complete pain.
The assembled bit and spares are waiting on the bench for a reassembly that I am confident will produce a working Century in good condition, and by the time I have finished the whole thing will have taken me a couple of man days in total - all for a motor that doesn't have a huge value in the first place.
It's come to my attention recently that there are people around who will undertake to strip and clean the muck out of a Seagull for around £30 on a fixed price basis; I can't help wonder how on earth this job can be guaranteed to take the couple of hours or thereabouts that would render this economically feasible - am I missing something?
How many man hours do you reckon it takes to completely strip, clean, reassemble, adjust, test etc a Seagull? And how many hours if you're going to brush the scale off all the castings, respray the flywheel, block, prop and gearbox?
Based on the unbelievable quote I have recently seen for replacing the top bearing in a small Mariner it's pretty obvious that marine motor engineers would be charging into the hundreds of pounds for the job.
Any thoughts?
