I have an IO-375, but I am not flying yet. When I was researching engines and props, I came to the conclusion that none of the Sensnich fixed props would work.

I think you could have a prop maker (Catto, etc) make you a fixed prop that would work with an IO-375.

For what its worth, I decided to use the Hartzell BA prop that Vans sells for the 180 - 200Hp IO-360s.

Hope this helps,
Jason

Default I have one

I now have about 70 hrs. on my RV-7A with a 0-375, 205 hp. It's a great engine and the folks at Aero-sport are great to deal with and very helpful. I have a 3 blade catto on it.
It will turn about 2850 rpm's down low. I'm planning to have it re-pitched to lower the rpm's. The best speed that I've seen so far is 212 mph. (184 knots) 4 way run with all fairings at about 1500' msl. Might be faster up high. I dont have the fuel flow red cube yet, but it does burn more fuel than the 0-320 I had in the 9A that I flew before. Someone with a cleaner airframe might see a little more speed.

Default prop

Hi Glenn,
Mine is a 3 blade Catto 68" Diameter x 75" Pitch. Craig said the target speed was 215 to 220 mph at 2800 rpm. He hit it right on the numbers.

Default IO-375

I've got the IO-375 195 hp in my 7A with a 2 blade MT prop. Inspection next week so I hope to fly it soon. With full power on the ground the prop holds RPM to 2700 rpm.

Default IO375

I also purchased an Aerosport IO375 with Superior cold air horizontal induction, and Eagle EMS electronic ignition/injection. I picked the IO375 with the 8 to 1 compression ratio so I could keep the HP up yet have more options in the future with the fuel issues. I have Cato working on a 2 blade prop for me. I am far from flying at the moment.
