Merc TWISTER CLEAVERS Or SIMILAR WANTED

[SUPERSPEED FX]

Im looking for any of the old mercury twister cleavers or similar. rh approx 10in dia X12- 18in pitch.
Does anyone know where i might find these old props??
Thanks

They appear on eBay about every 6 to 12 weeks if you watch closely.

Lower end pitch is rare, upper end (15 to 22) is a lot more common. Remember 15 at 1:1 is the same as 30 at 2:1 ..... 80+ mph. Your boat has to be capable of 80+ or you will lug the motor and burn pistons left and right. 10" diameter and larger doesn't really fit a Merc; they fit the Chrsyler racing lower unit. Best diameter for a Twister will be 9 and some fraction.

Which of the 3 Twisters do you have?

i have a few twister props
they did make 10" for them motors
gear ratio on a twister case is 1.25 to 1 also
commonly used on the later model high hp twister
and the original 140 motor which was the 1st v-6 design 12" mid with twister gearcase

i have 3 mercury cleavers right hand rotation
a 10" x 16,,,,,9 3/4 x 17 ,,,,,,9 3/4 x 19
that have never been dinged or repaired
that i will let go,,,,,,

The 1.23:1 gears were made for the 650x and 700x; I have never heard of anyone using them in a Twister. The standard gear ratio for the later Twisters was 14:15 (1.07:1) with 1:1 as the option.

10 inch diameter will only fit if you saw off the exhaust snout ... some of the last Super Speedmasters did come that way.

[john miffco]

if that was the ratios
then im wrong,,,,,
ill believe a man that knows the vintage motors

what i do know is i had 3 twister gearcase
all 3 was 1.25 turns of the drive shaft to 1 turn of the prop
thats how i checked them 20 yrs ago

i dont keep up on the vintage motors
i bought the stuff many yrs back and ran mid and cases on a v-6 drag boat
in the 80s
and they were super speedmasters with the snout cut to fit the props
and still have the 3 to sale
if he wants them
their just laying on a shelf

13:16 gears does sound like a good idea for drag racing :) ... a little more grunt to get out of the hole ;)

Ian, Are you still looking for these? I have two 15 pitch, 3 blade twister props, one is a cleaver and one is a rounded-ear type. Both are very nice, I am not sure of the diameters right now but I will check if you are interested.

[mercmack]

just reading your post, i am interested in your 15 inch cleaver, just what are you asking???:) :)

I used to run a 13:16 gearcase on one of my T2's. I have heard from different people that said they did not make one for the T2's but I owned one for years and a friend of mine still has it and I also have an old Merc catalog that lists them for the inline 6's.It shows a different part # for the 6's and the 650x/700x.

[Roy Hodges]

this shows some different ratios

[Mark75H]

I've been looking and I still haven't found a Merc part number that says it has 13:16 and a 6 cylinder driveshaft. The pieces do fit and can be assembled, but to my knowledge, no 6 cylinder SSM's came from the factory with 13:16.

[largecar91]

When I get home I will post part# .

[Mark75H]

The part number would be interesting, but a photo or scan of the literature that says it is a 13:16 for an inline 6 would clear it up for me.

[largecar91]

Ask and ye shall receive. Hopefully this is clear enough to read. Never sure when you resize things. Part # is 1624-5249A9.

[largecar91]

I will turn the photo or everyones neck will be messed up!
