How far apart are your drives? Are your motors on the transom or forward like mine. Where do you get a porpus? Do you know your weight?

I'm rumming 35 props

Is this boat new to you? new setup, motors, drives, etc...

What did the previous owner try?

What kind of power, and speed are you seeing?

Have you had a cat before?

What speed are you running when the hop happens? 4.25 above is VERY high imo. I agree with bobkats, we need more information. Do you have boxes? At 4+ above you better or I doubt you get on plane. Do me the video looks like it cant carry the bow. We need to know speed and setup. Post some pics.

Looks like the old Linder hop to me.

definitely the Linder hop.... 4.25 above the bottom is crazy high..

Brian, I think this is the boat.

It looks like he's swinging a 3 blade. That might be the problem. A four or five blade surface prop might allow more bow lift. Correct me if I'm wrong

Looks like you have a 31 foot boat and need to get it to quit porposing at speed. I looked at your video and would offer a few sugestions. If you have tryed all the quick and easy solutions, then its time to step up and buy the extention boxes. You should work on the X dimention and consider 5 blade props. Gonna cost but you will get more speed and more stability in the end. This worked for me- James

Tunnel tab?

i have tried a tab it didnt work. i am testing with the drives 2.25" above sunday. we will see how it goes. considering reducing prop size but 1/2"-1" to reduce transom lift but i dont want to increase slip.

What props are you running, 3,4,5 blades? Is your setup the one in the picture above SSM on boxes?
