Can Someone Help With Old "Brand New" Propeller?
 

I doubt it has any special value as a propeller.
It may be worth something to someone who restores ChrisCrafts. Look for a
ChrisCraft, wooden boat or boat restoration group/forum.

Hello,

My father bought a brand-new Chris Craft inboard motor boat around 1947 or
so, and took it up to the lake, and put it in the water for a test drive.
The
water level in the lake happened to be low at that time, and the first
thing
he did was gut the boat on a submerged log, and it sank straight to the
bottom. My understanding is that it's still down there.

Now here it is some 60 years later, and his parents' -- my grandparents'
house is being sold, and while going through it my cousin finds what he
believes was a spare propeller (screw, I believe is the proper term) for
my
father's Chris Craft, and brings it by the house and gives it to me. Says
he
thought I might like to have it.

It looks to be made of brass, measures 12" across, and has three blades.
It
has the number "645" stamped on it in one place, and "12L-H 12" in
another,
and "1947" in another, and the words Michigan Aqua****ter" (asterisks for
missing letters).

I know nothing about boats, and I don't know what to do with it. It holds
no
sentimental value for me, and is just taking up space.

I just wonder if it's worth anything, and if it is, where might be a good
place to try and sell it.

I found this newsgroup and thought somebody in here might have an idea
about
it.

Any help will be much appreciated.

Thanks,

Dave Hare

Check with a restorer or one of the restoration groups - it's probably
not worth a ton of money, but NOS (New Old Stock) does have some cache
- you might get a few bucks for it.

LOL, sorry to laugh at this unfortunate incident, but I can't help it. Why
is this funny? Newbie sinking his boat on a first outing?

Newbie gets back home,..wife says "where's the boat, dear" ..."at the
bottom of the lake, Honey, I sunk it" lol.

Its a Michigan Aqua-Master made in 1947. 645 is the dye/cast number. It is a
12" diameter, with a 12" pitch, and is a left-hand drive.

It is most likely made of NIBRAL, which is an acronym for Nickel, Brass, and
Aluminum Alloy.

Even modern NIBRAL screws are somewhat expensive. A modern 12X12 would cost
more that $350 new.

Because its an old original, you may find some Chris-Craft (or other vintage
boat) owners willing to pay even more for it.

Additionally, there aren't hardly any modern left-hand engines out there,
that could turn this screw.

Hope this info helps.

Netsock gave you some good info about this prop. Here is a little mo

The "645" is the dye/case numbre as Netsock said. It was also known as the
"Wheel Number". Basically it's a part-number specifying a specific prop.

It probably isn't worth a fortune - but to someone that is restoring a boat
that
takes that prop, to have an origional prop that has not been used at all is
worth something.

I tried to look up what model(s) of Chris-Craft this prop came from but
have not found it yet. ~ If you want to sell it you should try to find the
boat model(s) and adversite is that way.

When I was restoring a CC I did look on ebay for parts. And there often
are Chris Craft parts on eBay, so that may be one OK place to sell it.

Other soucres of info / places to sell:

The Mariner's Museum in Newport News VA (www.mariner.org)
has a "Chris Craft Archives" division run by Jerry Conrad.
Phone (800-565-6846). Give them a call, they will have any
information you need.

Check out Antique Classic Boating Society at (www.acbs.org)


These people sell Chris-Craft and other old boat parts, and might
pay you something and/or give you information:
Chris-Craft-Parts.com
ClassicBoat.com
OldMarineEngine.com

I'm not sure if your prop was from a "Sea Skiff" model, but
this site does have a part-for-sale secion:
www.SeaSkiff.org

Hope That Helps,
Gary

Correct Craft is the only tournament boat, I think, that uses a right
hand prop... due to the left-hand (CCW) engines.

Oops...did I get that backwards? Right-hand is the rare one?

Ok... :)

I don't know if I would call either one "rare", the right-hand-propped
inboard, which is quite common, requires a reverse-rotation (ccw)
engine, and the left-hand-propped inboards are a little more
straight-forward to do an automotive conversion job (still have to have
corrosion issues and spark ignition issues, & carb venting &
construction, all addressed).

When looking at rebuilds or new blocks, there is a $100.00 to $250.00
premium on the ccw engines.

Most stern drives have a standard, cw rotation engine.

Frankly, I've gotten a lot more help from this ng than I ever expected. I
was
hoping there would be people in here knowledgeable enough about boats to
give
me some sort of clue, but now I have a real good base of information to go
on. Thanks to all, and to you especially, thanks a *lot*!

Dave Hare

Glad we could help Dave, and welcome.

My only other advice is to set up a kill file, and some filters to weed out
all the OT stuff and trolls. After the garbage is cleaned out, your left
with some pretty good boating stuff.

Enjoy...

In our ski club, we have many Malibu's, Master Crafts, Correct Crafts,
Tiges, and Moombas...all are cw. The only exception, is one old
Natique...driver sits on the left side.

I don't know of any modern ski boat manufactures, that put ccw engines in
their hulls.

The premium for ccw engines, is for the reverse cam and oil pump. And
outside of the (pointed) distributor, and flipping the body on the pick-up
pump, everything else will work.

You say "most stern drives" are cw...I have never even seen one...did some
one make one at some point?

Later.

Correct Craft uses a ccw(reverse) engine, right hand prop(driver on the
right... "Correct"). MasterCraft uses a cw engine, left hand
prop(SHOULD have driver on the left)... take a look.

All standard Volvos, & Mercruisers, Alpha & Bravo types, use a cw
(standard) rotation engine. The upper gearcase gives a right-hand twist
to the vertical shaft (Alpha types - viewed from above), resulting in
the forward gear in the foot providing a cw(right hand - viewed from
rear) twist for right hand props in forward gear(back gear in foot
provides reverse).

Cone-clutched I/O's (Bravo & Volvo types)can have Left or Right Props -
the vertical shaft changes L-to-R for reversing.

Inboard cw engines "pitch" to the right when in reverse...the driver SHOULD
be on the right, to accommodate docking and other slow moving maneuvers.

If Correct Craft puts a ccw engine in, and puts the driver on the
right...well...that's just ignorant.

Anyway...thanks for the info.

I know they *can* make them spin right-hand, as most dual drives are
counter-rotating. My query was there ever any i/o manufacture that used ccw
engines.

Of course, I probably wasn't clear to begin with... :)

Here is your confusion... cw (clockwise) IS right-hand rotation - OF THE
ENGINE... as observed from the water pump and pulleys end - as intalled
in the family car or truck... this results in a left, or Left-hand
turning prop in a straight inboard as viewed from the flywheel end.
This is the MasterCraft and Mercruiser engine layout. This will result
in the driver being on the "incorrect" side of a straight or v-drive
inboard based on propellor thrust, which would cause the boat to twist
opposite the prop, or clockwise looking at the transom, and adding to
the driver's weight for a list to starboard.

In my time in the ProStar though, I never really noticed it, except
backing must be done on the opposite side from our Correct Craft. In
reverse, the transom walks right on the MasterCraft, left on the Correct
Craft and Century (Coronado).

Spin-outs have to be done in the opposite direction, too.
