[TheForge] costs of ownership question

[Jerry Frost]

Terry: This sounds like a strange problem, probably due to everything's 
antiquated status. I've never heard of a ship becoming so magnetized it 
causes the pistons to stroke out of line. That much magnetism would be 
easily measured from many yards away, probably hundreds of yards. A compass 
in the ship will point at the densest concentration of iron close by OR the 
longest continuous steel structure close. However if the same compass starts 
acting wonky walking down or to the peir I might buy magnetism. Heck, I'd 
expect the harbor master to have mentioned it messing with other ship's 
navigatino systems before now.

Degausing isn't so hard to do if necessary all you need is a loop of cable 
around an iron core. An electro magnet but running on AC current, maybe a 
yoke would work like for magnaflux testing but that's out of my range.

Egging the sleeves is telling me you have a bent crank, bad bearings or a 
call an expert situation. I'm no diesel mechanic but egged sleeves would 
have me on the phone immediately.

What did the ship's survey say about the aux engines? You DID have a survey 
done before you bought it didn't you? Please tell us you didn't buy a SHIP 
without having a survey done. A survey will give you important details about 
the ship and it's equipment/geat like age and make of auxillary engines 
availability and suppliers of parts. And that's besides their condition and 
expected lifespan. Just walking through looking at things isn't enough to 
tell you much of anything about a ship.

Here's hoping you the best Terry, wish I oculd be more help. Jer
