We were at twickenham!

you never beat the Welsh bud sadly on some occasions you do score more points.

Actually we did get on well, he applauded the English, I applauded the welsh, unfortunately half way through the second half his hands started bleeding

I'd never heard it before and I thought it was quite original and funny, which leads nicely to my original point about not beating the Welsh

I had a similar problem about 8 years ago, bought a boat fitted with twin 75hp Mariners that had been stored for about 4 years. The port engine was down in compression, ran is gently for a couple of hours and the compression came back , but after about another 100 or so hours the thing started knocking. Got it stripped and the mains bearings were shot, all rusty along with the shells. Apparently this can be quite common with engines that have been left for a while.
Best of Luck

the fault you had is similar to mine however my big ends went within a few hours rather than 100 or so. i would venture to suggest that if the bearings or bearing surfaces were visably quite rusty etc then the engine would not last very long at all. however minor corrosion will decrease the life of the bearing/shell and there is no exact science on how long it will go on for.

its all a big gamble and minor damage from corrosion may not show itself in a failure for some hours so it is just best to bare this in mind when putting the boat/engine thru its paces.

if a strip down and replace of shells and rings or at least checking them was an option then this would be a good way forward for sure but not everyone is able to do this themselves and getting a dealer to do it is costly.

good luck

Hugh, it won't have shells as in a 4 stroke. It'll be needle rollers and they run between the bigend of the conrod and the crank. If there's severe rust, it's a major job. If the crank and rods are only minorly damaged, it is possible to hone them and bring them back to life relatively inexpensively if DIYing is an option. Needle rollers can be purchased from bearing suppliers in quantities of 100 for not too much money.
