I never ran the ET wheel,but I am running a worked 28 chopper. I have a carb 2.5 200 with the heads milled,stacks on carbs,exaust bluprinted,boysen dual reeds. The boat has a awsome hole shot. I only ran it by myself with a full fishing load and batewell 1/2 full. The boat shows 65 mph a 5 grand,75 at 5300 with a 1/4 throttle left. It gets too much chime walk @ 75 for me to nail it. I have 14" set back with a hydralic plate. Tried from 1/2 below to 1/2 above on prop shaft runs best even to 1/2 above. I guy at the lanch with a drag 300 on a STV ays the mold work on my bob's needs to be perfected.
