stick some boxes on the damn thing, it will help a lot !

i apologize for bringing this topic up again, i see that it has been dead for several years...

I have a 94 TG with 780hp blower 540's and Teague platinum drives, with labbed props, i can get 82GPS on smooth water. i still have a porpus problem though, should i look into putting extention boxes on?

this boat is new to me, and im new to the "go fast" side of boating, so i apologize if i ask a dumb question.

What props are you running? I would have bet that it would be faster than 82.

All straight bottom cigs hop until 62-64, then they lay down and run flatter, I run tab until 60, then I can raise tabs up all the way if wanted. Running 15 r, 17.75 diameter, 5 blades

Zero, how deep are your drives relative to the bottom and do you have boxes?

Yes, curious on this one too. I have porpoise problems.

17.5"dia 32P - 4 blade Merc cleaver, 5s on boxes even with bottom, 1000hp a side

Seems to run pretty good above 72-75mph, but bad porpoise where I want to cruise at 65mph without burying the tabs and using more RPM to cruise.

I want to try drive spacers, any before and after experience here? I also have a set of 32s to send to BBlades that need cupping to help planning, any experience on what was done to props to also help stop the "hop"..


<---- See, look how bad it hops in my avatar!!!

If this was true I`d put on my spacers in a second. I find it hard to believe however that putting the bullet deeper in the water would increase speed unless it really gets that hull out of the water that much. I did not notice that when I had the spacers on .. boat planed a bit better but speed was not increased. It only increased with higher X

Wild - did the handling improve at all with the spacers?

Mine loses 2-3 mph max using tab to stop the hopping.

The lower "X" gives you a little more leverage. at cruise speed the hull run a little deeper in the water. With the inherent HOP issue of all Top Guns this makes things worse. Lowering the "X" 1-2" will give you more forward push helping the HOP with a little tab. Then try prop work. I believe Gary (RPM) has a set of spacers if someone needs them.
