I wouldn't stand in the way of anyone who wanted to buy another tool, BUT
the impact gun I was given as a present was feeble compared to the monsters
used at the tire stores. When my tractor wheels needed to be removed, I
found that the classic X-shaped lug wrench, abetted by a ten foot length of
tubing (ID big enough to go over the lug wrench sockets) removed most of
them and twisted off the two that were solid blobs of rust. Arrange things
so that you are lifting up on the length of tubing. It might help to have
someone else steady the wrench until the torque is applied but a cardboard
box will work too.

They
sometimes wear out and cause slippage as you mention. In which

a
prop
shop can install a replacement insert. The other and less
likely
is
the
splined coupling on the crankshaft of the engine. The drive
shaft
to
the
lower unit mates with this coupler. It is a neropreme filled cup
that
also
absorbs shock. This requires pulling the engine to replace the
hub
and
require a hoist to lift the engine. Hope this helps.

Don,
It appears that my prop is missing what I would call an expansion
ring
on the back hub of the prop where the exhaust comes out. Could that
be
a problem?

Likely not related. Put your spare prop on, go for a boatride and see
if
the
problem persists. It's likely a worn hub and any (decent) prop shop
can
fix
it.


Any idea about the size of the nut that holds the prop on? I don't
think I have a socket to fit it.

Whenever you go boating (besides wearing PFDs), you should be carrying a
toolbox (so you can at least perform emergency repairs) and the tools to
install your spare prop (you know- that other prop you always carry with
you). If you're not already doing this, make sure you do the next time
you
go out boating (to safeguard the trust your passengers place in you).

Pull up to an auto parts store and they'll be able to select the correct
size for you.


The nut turned out to be 1 1/6", but It's so tight I will need and impact
gun to get it off.
I'll get my spare prop on this weekend to see if it corrects my
problem.
