Freakin legalities are so bad now days that it's almost hard to post opinion.
IMO a 76 stump puller will out push a 75 3 blade h! The balance will give you fits trying to put a single stump puller on a boat though.
I sure hope this wasn't a compare to a 3 blade 76 stump puller vs a 3 blade 75 h?
That's about a 100 hp on the northern end of pitch and props even with a 2 to 1.

Hi Cycoles,

What engine were you wanting to put the 76" Stump Puller on, and how many blades? Is this for your 220 GPU engine?

I can recommend a few options for max thrust on the 220 GPU. (Sorry if this is not the engine you are asking about)
1. Excalibur 3-blade in 72" diameter ($1790)
2. Whisper Tip Narrow 2-blade in 72" diameter ($1690)
3. Whisper Tip Narrow 3-blade in 68" diameter ($2290)

And if you were looking at used propellers, some of our older blade styles that would be good for the 220 GPU:
*I'm always happy to look up history on a used propeller if you are looking at one for sale.
1. Super Snapper 2-blade in 72" diameter
2. Super Snapper 3-blade in 68" diameter
