Repowering

I have a mid eighties Ariens ST824 with a 8hp HM80 tecumsah motor which is getting tired and I would like to repower. I was originally was going to replace the motor with a 8hp predator motor but I read htat you can use the y 1/2 hp predator and a sleave adapter for the shaft.
I would prefer to use the 6 1/2 because it costs alot less but want to make sure it has enough power.
Any thoughts?

Haven't used one myself, but everything I hear is that the 6.5 rating is understating things.

You may have to drill new holes for mounting the engine, but for a 24" auger housing the Predator 212 should have about the same power as the old 8hp Tecumseh.... (enough power IMO).

There will be another set of holes already punched in the Tractor unit that will accommodate the 212. Cut the existing studs off after the original 8hp is removed. You'll have to sleeve the crank to get the original pulley to fit the 212. Fairly Easy Swap. The 212 has Plenty of Power for a 24" Machine.

the 212cc will have more power then the old hm80 ever did. should be pretty much bolt on only needing a crank sleeve, the existing studs should be long enough but if not cut the old ones out, insert 2 inch 5/16-24 bolts from the bottom and tack them in place from the top so they wont fall through when you sit the engine on the frame(thats what i do at least make an already easy install even easier)

From everything I have read on here a number of people have used them on 24" wide buckets. Remove the Air filter and rejet the carb to .032 and you should be fine.

In my experience and as Jackmels stated the 8hp Tecumseh engine has a different mounting location than the 7hp Tec or the Predator 212, therefore the studs will need to removed/cut off and new ones installed on the further forward set of holes.
