Well ordered a set of 4x4 from Hill marine at 24 pitch. The big decision to go with Hill, is they did call me back and will also change me out to a different pitch at no cost other then about $30 for shipping each way.

does that mean others didnt call back?

Yes, no return email or phone call nothing. One I called again and they to were in agreement that the 4x4 was the way to go.

Well 8 blades just has to get it done....is there cupping on these multi blade species?

Found out Hill Marine are the ones which actually make the props in house on CNC machines. No cupping but rear prop uses a progressive pitch design. The front and rear prop design is of their design. Talked with "Dad" for about 20 minutes, real nice guy and is a retired teacher. The design was originally made for Yanmar diesels, and was told that if they work they would have a 10K contract (forget if it was a month of year). They then took them to the Miami boat show years ago and have averaged 60 sets a month ever since. Just like Mercs XR props it's my opinion all 4x4's you see folks selling come from hill marine

Interested to hear the results.

Alldodge, cool to see you ordered a set also. I am probably looking to go to 26s at this point so I have to put a call into Chad today. I got some time in on my 4x4 24s and she pulls on plane pretty hard, faster than ever and to be honest with upping the pitch I doubt I will notice much because she gets up quick at 1/4 throttle. I want to push my cruise up a bit so we will see.

Will be interested to hear how it does with the 26. What does your boat weight?
