Predator repower

Hi all, new to the site.
I just purchased a Murray 10hp 29" for $35 that has a 10 hp Tecumseh with a broken rod. I purchased with the intention of repowering with a predator motor.
I've read great things about the predator 212 cc 6.5 hemi but didn't know if it would be enough to power this. I was considering the Predator 8 hp 301 cc as a repower but everything I read says the 6.5 hemi is closer to the 7 - Predator repower-20180827_214815_1535422016650.jpg8 hp mark. I know the shafts are different sizes and would need a collar for the 6.5
I haven't been able to find much about repowering larger machines.
Thoughts?

If your machine was a 24" or maybe a 26" I'd say go for the 212.

Because a 29er with a full width's worth of heavy snow might push it to the brink

Plus the bolt pattern and crank height are probably very different than the original 10hp engine too (?)

At the least I suggest the 301, an impeller kit, new belts and let 'er rip

Maybe even the 420 - looks like the chute direction rod is out there a good distance and should still clear the engine as it runs past it

This is going to be a cool project so whatever you choose to do please post your progress!

While I think that the 212 would do a good job ( It rocks on a 24 in and 29 isn't a big difference.....just take smaller bites LOL) a bigger engine will give better performance....but a 212 is easy and cheap and reliable.....and more oomph then you think. I've seen 212's on 32 in Ariens. and they really push the snow.

Our old friend Fearless Front had a video of his 212 Predator powered 32 in Ariens

I think I'll try the 212, I have a coupon for $97
and you can't use the 20 percent off on Predator.
This makes the 212 more desirable, I just hope it does a good job.

I've got a 5.5 Chondra from HF that I repowered an ST 824 Ariens with in 03 or so. Plenty of snap, never let me down, will go through deep heavy snow with not a wimper. An impeller kit is highly recommended. I put in an adjustable main jet, but stock just run on half choke. Good luck.

There's no question the Predator engine is bang-4-buck. However, in my humble O, the 212 cc is too small for some of the sizes being discussed. There's no substitute for torque and moving heavy snow requires torque, the more the better. I just don't think 212 cc is adequate for a larger thrower, for sure not a 32 auger. It's not that you can't get a lot of horsepower from a small engine; just look at formula 1 engines. But those 1.6 liter engines make their 800+ horsepower at a screaming 12K. Whereas the good old American V-8's made power at a noise-friendly 2K rpm. Having torque means you can throttle-down, have a bit less noise in the 'hood and still throw a foot of snow twenty feet.
