I have recently been looking on e bay for an engine suitable for reconning and I am suprised how many e bayers who believe that silver,blue or green paint make an engine "as good as new". Some are even shown for sale with the paint still showing on the temporary wooden bearers or pallet.
Having dosed it with paint they then put a premium price on it!
 
Just because there's paint on the pallet doesn't mean that the engine hasn't had internal work done (or that it has). Caveat emptor.
My new 2GM20 from yanmar had a final coat of silver paint covering wiring, hoses, alternator et al - didn't mean it wasn't a cracking engine though.
 
Thats nothing, I once saw a surveyors report that said the engine was a BMC 1.5, 4 cylinder, single acting, trunk piston, compression ignition oil engine.
It actually had Thorneycroft in big letters cast into the rocker box!

I understood that some Thornycroft engines WERE marinised BMCs, later ones mostly marinised Mitsubishis.

And Yanmar spray their new engines AFTER they have fitted rubber hoses etc, which means you get flakes of paint coming off as soon as you run them. At 9 years old on mine most of the paint is now off the rubber bits.

Beta paints aluminium parts without any primer which means that sooner or later you'll have the paint coming off those bits.

Must say, 10 years after installation, the only paint coming off the Beta is from the rubber bits. They did give me a tin of touch up paint when I bought the engine but it's still unopened in one of the lockers.

Stops the **** getting into engine internals during painting!
 
Perhaps I am too particular as when we did car/van sales we did colour changes including engine bays. Using Masking Tape which is obviously too expensive for the Marine Industry to use.
Last year I went to the Preston Boat Jumble and there was a display of three reconditioned engines and all three looked as if they had been sprayed by a blind man.
Any intentions which I may have had about buying from them evaporated immediately. If they cant take pride in how the outside looks what will the inside be like.
Mind you what they probably do when they are taking an engine to a show is get any engine off the floor, quick spray with thinners, then give it a blow over for the show,

Overspray on an engine which was 25 years old (Iveco) made me get rid of a boat.
The lower cam belt roller still had the red Iveco paint overspray on it from new, which made me conclude that it was the original and had never been changed, so I tried to buy a new roller, I tried Marine Engine Suppliers, Industrial Iveco Engine People and Iveco Van/Truck parts people and all three sent me a roller which was completely different than the original, and non of them fitted.
So as the engine was running fine and there was no sign of wear on the roller I sold the boat knowing that at sometime in the future the lack of a suitable replacement roller would perhaps necessitate an engine upgrade.
 
I was on a boat which came close to sinking, the reconned engine had been nicely sprayed but they sprayed over the old perished hoses which sprang a leak pumping water into the bilges.
