What are the specs of Mantyla's redrive? Paul, I checked the ACRE's
website but you don't have a link to this guy.  What does he sting for the
plans?

Good thing I saved this message. Some people don't read or save them all
:-)

Hello Paul,

I've never seen the Mazda engine up close, but I would imagine that with the
right adapter plate the drive wouldn't know what engine was driving it.I
designed the drive to accomodate about 100-120 hp. Is this enough with the
Mazda engine??The gears should be ok, but the prop should be a light weight
type such as a Warp Drive or a wood prop.This will keep the gyroscopic
forces low.If reqired the output bearinge could be beefed up.
The specs are as follows:

1)ratio-2.21:1

2)weight-25lbs

3)length-11.5"

4)gear set- Chrysler 727

5)lubrication-via engine oil pump

6)prop flange-SAE#1

7)housing -6061 T6 billet

8)vibration damper-Ford V6 bronco clutch center(may have to change for more hp)

9)approx cost of materials and parts-$400.00

10)cost of plans-$75.00USD

I have attached a few pictures for you to review.
