Bill, you have run almost every prop on the market except a thin blade 5 or 6 blade. Try a Sabre and Excallibur out and then YOU will be the foremost authority on what prop to run on a SV 0-540!!

Hi Mr Bill,

Sorry, I've absent from answering your questions. If you are looking for the increased smoothness that is inherent to 3 and 4 blade propellers, I can make a few suggestions for you to think about.

If your 540 is a parallel-valve, I think the 3-blade Whisper Tip Narrow (10" med wide blade) may be a little too much blade area to give you an optimum blade angle for maximum performance. This is propeller is what we like to put on a high HP angle-valve type 540 or 520 aircraft engine.

If you want the ultimate in smoothness and performance, I would recommend our 4-blade Excalibur propeller system in 72" diameter. This 4-blade propeller uses our 5.5" wide Excalibur blade style with our exclusive X-Core™ composite technology that gives the blade extreme strength while also making it super light and stiff. The Excalibur blades will spin up fast to give you instantaneous thrust, and with the wider blade width, they will also give you that excellent mid-range and low-end performance that wide blades are known for.

Sincerely,
-Patti

Sidejobs ran one on his very healthy Caddy.
You may want to search his posts, there was quite a bit of info you can likely use.
Here are a couple threads with some info as well.

I had a brass nut come off the motor the prop shoot it thru the oil cooler- lucky in went thru the fins only. So I wonder how the 3 blade performs verse the 2 blade. right now I running a 74 2 blade WT blade around 10 wide at 3000 on about 13 degrees
I more interested in fuel but would like to know power change.

I ran an Excalibur on my sled for almost a year. I loved the prop but it didn't play well with my motor. I would highly recommend the Excalibur. BTW, I've got one for sale. Brand new hub and hardware, Armor coat on blades.

I have tried an NGH and Q. Both were 72". I would definetly go with the Q. If I was starting from scratch....I think I would try three of the 4cyl version NGQ blades.
