Hi folks:

I've got a thread on my PPG quad build:

and I've got some questions about mounting my engine. I've got a Subaru EH99 industrial engine:

I'm looking at a manufactured PPG and how they've mounted their engine. It looks like they are only mounting it by the holes in the back case cover and not using the mounting holes in the bottom of the engine:

Is this structurally sound? The other models I've seen all have the engine mounted by the bottom bolts to the PPG frame and the redrive unit either mounted to the back of the engine of the frame of the PPG.

Thanks,

Michael
