I know, I don't have the tool and our launch is next Saturday. 

First option, thought I could pull the shaft and get the bearing out - not
easy!

Second option: Just sent email to eMarine for the tool to be expressed
shipped to a FedEx location in Buffalo New York. Will drive there next week
and pick it up if possible.

At this point I am willing to pay duty, taxes and price of tool to get it
done.

Ted - Why are you pulling the shaft?  I thought you were just replacing the
cutlass bearing.  The shaft doesn't need to be pulled to do that. - Allan

Good news at the boat this morning. I used an impact air gun. Just used150
psi air compressor from home depo. The  nut came off with ease. 

The prop was next and I put the prop puller on real tight. Went for a
coffee. Came back three light taps and off she came. I applied pb blaster
before coffee. 

Thanks everyone. No heat required so I guess I lucked out. 

Next step. Pulling the shaft out.

Jeff you said the shaft will come out past the rudder. I have tried to pull
it out past the rudder on the port side. A substantial bent in the shaft.
But I could not get it out. 

Is starboard or port side any different?

Is the bend normal?

If I force it out will it go back in? Or is it just as difficult to get it
back in?

there with the torch and heat it for a long time, you're simply defeating
the purpose and will damage stuff. Don't point the torch at the cutlass
bearing.  Again, Common sense there.

it many times. We're talking 15-40 seconds time range with MAPP gas and a
little tap with a metal hammer to set up vibrations.

that the heat can damage the rubber in the cutlass bearing.  I have changed
out 4-5 bearings now and for 2 of them, we used heat and that was the only
way those 2 props were coming off.  But the reason we took the prop off was
to change the bearing anyway so no harm/no foul to the bearing.

day, my neighbor decided to use his props as depth finders and now needs to
pull them. The local guru told him don't eff with heat, soak it with PB
BLASTER then put a quality air impact wrench on it. He stated he has even
resorted to running a generator to run an air compressor to run the impact
wrench.
