Small ear vs. big ear

[oldskier]

What are the running characteristics of a small ear vs. a big ear, and what application are each suited for?

A big ear moves more water, why would you need one that moves less water?

I got a small ear 26 and it will turn up real fast. Gets out of the hole real good and gets gone. Once it gets to about 50-60 it starts slowin down and will ony run 70 top end. But its hell out of the hole.

The larger ear is supposed to Carry a load better.=more blade area. If you have a strong enough motor you can propel it faster and move more water at higher RPM. If you have smaller blades they can be spun even higher rpm but more suited for lighter boats. On your hull you could use either one I would think. The newer large ear Chopper11 has a flow torque hub for all applications. Your probably right about why would ya move less water because they don't make the small ear any more. Hears a link identifying all the choppers made with there numbers and sizes. http://69.24.70.63/adamsdock/chopper.html

The big ears have more blade area, more lift, and are stronger. Ron Hill told me that the small ears will break with big power.

Your boat is small and light and might be suited to a small ear.

I've tried both on my SS2000. Both the 22 and 30 big ears made it spooky. Not out of control chine walk, but never still. My boat runs great with small ear choppers. I've tried 20, 28, and 30.

i didn't like a big ear 32 on my alley ss either..... it was to hairy for me.... to get it to run right i had to trim it up to fly, but the ss really don't like to fly with the bow up that high..... just the wrong prop for a ss IMO.. never tried a small ear..... i have a 30p small ear i need to try....

When I first got to this forum in July, I thought a big-eared chopper may have been someone who went to a Wal-Mart south of the Mason-Dixon line.(Just kidding, everyone!) I have since done some reading, and some careful listening, and found the above references to be accurate. For my application on a true tunnel hull (no pad) and a gross weight of 1400 lbs, with a small by contemporary standards 115 hp, I'm going to try a small eared chopper first. It is by no means cast in stone that this will work first thing out of the box the best, but that is part of the fun, isn't it?
