Is the 1440 back cut? Or does it over rev with the 1440? Couldtry a 40x53 I believe.

I have a zipp 12 with an os 18 tz turning a 40/56 prop. It does great, once I got the pipe to the right length. High nitro mac pipe with the cone at 2 1/2 inches from glow plug. Started with a 38/53 then went to 40/53 and to the 40/56.

The prop is back cut motor only screams were did u get the 40/56 prop from ran a 215 not bad but I think there is more in the boat thanks for the info

I run a 12 engine. When I startedv with the boat I used a 215, I run 1440 back cut /detongued and pitched up a bit. Could try a 1445 or maybe a h2 or h4.

Zipp kit 440 is the 40/56 pitch,worked it a little, tongue removed, blades are smaller, let's the engine turn it.

with the TZ OS you won't have problems to turn a 1450(46mm).Gill

would have to be a stout .18 to turn a 1450 I would think..

 

[anthony_marquart]

cut way down it might work.. we run 1450's on out 21 riggers

 

[RodneyPierce]

true, but the power difference between the two is pretty decent.

Jon,

An ABC 42 x 55 runs very well.

Thanks,
