Spun prop hub?? How frequent??
wheels
I have heard of large outboards having problems with the prop spinning
on the rubber hub insert. This disables the boat and requires the
prop be replaced. How many of you have had this experience?
Also, Mercury now has a new design called flow torque II that is
supposed to eliminate this. It uses an nylon spline insert that is
designed to shear on impact and be easy to replace. Any opinions on
this. should I spent the $475 for a new Mercury Mirage prop?

Spinning a prop should not require you to buy a new one. The prop can be
rehubed for about $ 100. you might try to hve a brass hub inserted. It is more
suited to high perfomance props. I had one put in my mercury SS and it works
great!.

I tried a higher pitched prop than the one I usually use and it spun out of the
hub and I had it replace and it did again, now I'm afraid to try it again. It
might hold up on a lighter boat, mine weighs about 7000 lbs.

I don't have 7,000 LB of boat, but I had an outboard
mechanic explain to me, when I spun my prop, that drying was
my problem. I trailer my boat, and the fact that I keep my
boat in a garage makes the rubber joint dry out. He said
that he works on commercial fishing boats, and they rarely
spin their hubs. The reason is that they keep their hubs in
the water and the rubber never dries out like it does in a
garage. I have never respun a hub so far, they usually hold
up for the rest of the life of the prop for me. I rarely
hit large things, I just sort of nick it to death, over a
number of years. Lots of shifting sand bars around our
area.
You may want to check out the possibility that the hub was
not done properly. If the metal parts are not clean, the
bonding will not be very strong. A check of the shop that
did the job might reveal others with the same results. I
have never had a problem with a rehubbed prop, so I have a
pretty good trust of them.
The weight thing might be the problem, if that is not the
original prop with your rig. Higher pitch will put more
pressure on the hub, if the weight is the problem, you will
need less pitch, not more. I have a 2500 lb boat but I have
pulled many double sets of slalom skiers out of deep water,
without a hitch, rehubbed or not. I can tell you, that is a
lot of pressure on a hub. The last hub I spun, however, I
was on a leisurely fishing trip, taking off very slowly...
go figure.
Hope this gave you some ideas,
Charles

I know a good prop shop on Lake Erie. If you need an adress just let me know. I seem
to hit everything in the lake.
Happy Boating,

I have owned and operated high horsepower outboard botes for several years and
have never opps never say never spun a hub. Currently I am running a 200+hp
black max and am running a 26 pitch four blade quicksilver prop that pushes my
bass bote in the mid seventys.
This does not happen as often as one might expect. Some of the old timers
experinced sheer pin break off however I have not heard of any hub-blow outs
for quite some time on the tourney-bass trail. phil

What engine(s) are you talking about here. I've had problems with '95 model Merc
225 and 3.0 liter outboards spinning hubs. If any one has had the same problem
please let me know.
Take your prop to a machine shop and have them press out the hub. Stop buy your
local Merc marine dealer and pick up a new style hub for about $30.00, drop it in
and you back in business.
