Re: Mercury KF7 rusted tight powerhead

[green-thumbs]

Thanks for the offer. I have no immediate plans other than to get powehead apart while doing as little damage as possible..

The basic problem of what techniques work best to for a stuck KE7,KF7,KG7 or KG4
still remain. I do know that exhaust cover screws are known to snap off…leave them
alone for present. I would appreciate any insights from those more experienced
with stuck powerhead of a motor in this series.

Lacking any better ideas I probably will try grease gun. From what I can see and conditions
so far encountered it is likely that both pistons are stuck by rusted rings, upper and lower
rod bearings seized with rust and same for crankshaft bearings. I am hoping that careful
gentle efforts will salvage whatever can be saved. Worst case all junk and wasted time
and material.
Thanks
