corrosion and torches

[gofastsandman]

Hi all,

Well I`m stuck. Literally.

`96 rude 150 Fast track trim and tilt assy.

The motor failed and I am trying to remove the unit.

Two weeks of various penetrants and banging with a 3 lb. sledge and a brass drift have been fruitless.

Put an air hammer on it today and got the lower pin to break free from the transom bracket collars. The center tube is holding fast.

Not mine, but here`s a pic.

There is a 1 in. shaft that goes through the casting at the bottom of the hyd. manifold.
Lots of white corrosion in there.

Mapp gas burns 300 F hotter than O/E but then you have the pressure advantage of a pro torch which I don`t own.

So,
Any thoughts?

Cheers,
GFS
