Yea....It seems like my Top Gun needs to lift the bow more,not lower it. Vs on boxes

After months of experimenting with short drives and shims, we finally lowered our drives 1/2" lower than our original stock X.
We picked up speed at this height and experienced way less porpoising, with the addition of a small amount of hull hook removal we completely cured our porpoising .

Good info..Thanks...I have access to 1" spacers I will try this spring

if the boat is porpoising, wouldn't you want a higher x to lower the bow?

Know, you need to pick up the bow and keep it there, with a high drive height you don't have the leverage to keep the bow up ,so it acts like a see saw, up then down never continuously carrying your bow.
Before you spend a ton of time and money like we did and many others before us re-rigging our heavy Cigarettes to lighter stepped boat specs, I would give Tres Martin a call all these boats are a little bit different.
He was the one that finally suggested we lower our drives 1/2" deeper into the water than stock. He was dead nuts on, we went from 83 to 85mph and running like flipper, to a best of 94+mph GPS with new X vr our 2" shortie drives, and she requires zero tab at cruise speeds. Good Luck!

we were planning on gettin 12in set back boxes with a raised drive height. this boat has no problem keeping the bow up...we just need to keep it down

wildwarrior; do you have a picture to show what height your drives are at in relation to the boat? thanks

This is it ,i'm not sure you can see much!

ours...

The first thing I did was call Tres Martin. He said bring it down,he could take care of it. I'm a poor working stiff tho..So I cant..
I dont blame him a bit..Thats how he makes his living
