A heat gun will not harm the paint. It actually melts at a fairly
low temp.
I just put a pipe wrench on it and heated until it
turned.
And Frank yup that was it compression thread

James and all the trick
to the shaft is a heat gun.
The first one I tore apart like james ended up
digging out the threads yuk
Then I tried the heat gun. What ever the
glue is that they stick it in is
real low temp stuff.
I heated
the base and it unscrewed real easy. Nice clean threads and
all.
And also the thread is a common thread just can't remember what
it is at
the moment.
I know I found a fitting for it at the local
hardware store.

Hi Frank.
They come appart really easy......appart
from the shaft.
Take off the anode and prop. Unscrew the 2
long bolts that hold it all
together. The endcap houses the
bearing for the end of the armature and just
pulls off (take care
with the spaceers as they fall out)
Then the prop end just pulls
off. The motor brushes will snap in as they
are spring
loaded. You can now get to the connections to remove them.
Now
you can just pull out the commutator assembly which is a bit
awkward due
to the magnets sucking it back in. Just push, it
will come out.
The top motor controler part is even easier.
Just 3 screws around the
base. Pull it off and the wires can
then be pulled through the shaft. You
can also take that
bracket off now.
This is the awkward bit, the shaft. I
tried to unscrew it at first.
Forget that, it will never
unscrew. I mangled it so bad that it was all
shredded and
eventually i was forced to cut it off flush and dig all the bits
out. The second one i found "the method" which
is...
After removing everything, cut the shaft off flush, or
almost flush and
then tap with a screwdriver into the joint away
from the threads. It cracked
into 4 pieces and came out really
easy, all nice and neat. I think the
mistake i made was to try
and unscrew it, it just broke it all and made a
mess.
I just
updated my site so the pictures are on there, its easier than
trying
to explain it!
Regards
James

Hi James. How do
the Minnkotas come apart. I haven't tried to take mine
apart
yet but if you had any tips on dis-assembly, that would be
helpful.Thanks.
I've been busy assembling the stainless ballast
tank pieces for a few days
with many days yet to go but at some
point will need to tackle the motor
modifications. Frank
