Y'all just might want to consider a Warp drive three blade Prop. I just put one on an 0 290 D and a little T 18 Thorpe I had a Caddo prop and when I was running the engine wide open in the driveway, it picked up a three-quarter inch nut and shattered the prop. They were 8 to 10 weeks out on delivery. I ordered a warp ground adjustable that has been a really good prop put me at 140 mile an hour at 2450 RPM. The two blade Cato Prop gave me the same performance. When I step up to an 0320 I won't have to buy another Prop. I'll just readjust this one. On an 0 320 with that Prop they're getting about 160 mile an hour and on an 0 360 they got one out there and he's getting not quite 200 mile an hour. Sent from my iPhone
