-2 shorty?
 

Its about time for a drive, and being i have nothing. Wondering if a -2 on the transom will work or has anyone tried one on the tantrum. I dont care much about drive ability, getting on plane, or acceleration. just top speed, 740hp 700lbs torque. don't want to buy an standard xr, just to trade it for an imco. and i know its all trial/error but short cuts are nice

I'd buy a new hull. I don't think that boat is made for speeds over 80mph.

don't recall asking that, prick

+1 lol!

I bet you have the nickname, "Seagull" don't you?

dont worry Ed, i wont run wot

The Patchy guys are just jealous because your boat company is still in business. :evilb:

Where is the prop shaft to the bottom of the boat and is the transom notched?

Tantrum is a conventional 24 degree hull no notch, all I have is the crank center line, (x dimension) being I have no drive. It's pretty deep, boats short, and light. So thinking -2 probably the best?

had a 25 and over 80 is no problem maybe your 28 patchy is scary if you can get it over 80!!!

What is the X dim then????

Well, no one else is tell'n ya so I guess I will.
There has been alot of talk on here about spacer's on the 25s and I believe Gordo(the resident 25 guru) has said many times that they do no good. I would PM him he is the man for 25 set up's.

Gordo says the Extension box does no good. I beleive he has a high X-dim. I think its 19.5", that is the most alowed by APBA.
Now a std. length Bravo is 21.5", from crank to prop center line(c.l.), so his prop depth is 2". I cant remember if he runs a shorty. What ever he has is going to be a good starting point, he has tried everything. I have an extension box so my info won't help you.

You need to find your X-dim. Crank c.l. to keel/bottom of boat. I have heard some 25's have 17.5" X-dim. if this is the case use the -2 to get a 2" prop depth. I am pretty sure all of this is correct. Good luck. Im sure Gordo will chime in at some point, but that could take a while.

following the keel out even with gimbal, crank center line 15.5". Or 7" from bottom of gimbal to keel. Did Pat set all Tantrum dim. different for customer purpose? Or just the all out race version.

di(k!

ya think?

I know!

Actually this thread is named after him....."-2 shorty"

:evilb:

now thats funny

I said it before and I will say it again.. TOOL........

But they allow him to pollute this site with his BS.

Lots of love on this forum. Your guys are so brainwashed by your cult that your incapable of actually discussing the topic with anyone but yourselves.

I recall reading that the 28 non-stepped hull, at one point, was not rated for speeds over 80mph. I'm pretty sure I read that right off the AT website, although it is not up there now. Pat correct me if I'm wrong here. What is the max speed rating of a 25AT? Do you guys even give a chit or would you rather wait until someone gets killed? Since both the 25 and 28 are not much different I thought the subject was worth bringing up. I know that the old 32AT had a hook in the hull. Does the 25AT have a hook? Its pretty hard to get an old straight bottom boat with a hook past 80mph. And if you do it could cause excessive stern lift. If it does have a hook I'd remove it or start over with a new hull. Don't tear up a good pleasure boat trying to turn it into a race boat.

I'm just asking the question. Its not something to be ashamed of. Pride is not going to be worth much when your dead. The 28 Apache is only good for 85 ish and starts to get a little loose. That was pretty fast back in 1990. IMO you really need a lot more running surface for speeds over 80mph.

:popcorn:

Now I get it.

:argue:

Ok, stand corrected.

:7160::chill-pill:

You are unbelievable!

My 28 straight-bottom runs mid 70's and at that speed I can take my hands off the wheel and steer it with my d!ck! Where the hell do you get this stuff from?! I knew the guy who owned OCD's boat before him and he ran mid to upper 80's without and ill handling characteristics. The crap you spew about AT's is getting super old.

:hijack:hu? I'll just post gps when I,m done.

I can tell you the 28 runs very well in the mid to upper 80,s. I hope to see 90+ this year if all goes well.

alot of boats were not made to run over 80, but who cares if we followed the rules then we would live in a perfect world, and as far as ive noticed were along ways from perfect so lay the sticks down, and if you need a -2 shortie ive got a pair listed in the swap section.

Get the shorty. with that X, I 'd think its worth a shot. And you can always add a lower spacer. I have a 1.5 and a 2".

I second that, if your at 15.5'' yes a 2'' shortie will help. its what got my 24ol into the 80s, I had a 15.5 also. my boat few level in the rough. my saber had the same thing. the old owner put a 2'' on and pick up 3 mph. I set mine at 17.5'' with the new konrad and it gets on plane with ease. also put full hyd steering on, if you don't have it. good luck.

It could also be an opinion" that you have no testicular fortitude.
I will start by agreeing with you in that 80 on the water is fast, and a speed that should be respected- in any boat!

However, These days there are everything from pontoon boats to jet skis that are capable of running over 80.
This is not your grandfathers pastime anymore.
When offshore racing was in its prime, one of the largest, and arguably the most competitive classes was Factory-1. Over 20 boats, all 24' to 29' in length, and most of us running well into the 80mph range. There were racing incidents, just as there are in any motorsport. However the 25 Active Thunders have all done very well on the race course, whether it be Lake of the Ozarks, Lake Erie or Key West. There have been a number of 25 Active Thunders that have been very successful on the race course.
I've done very well in my 25 Active Thunder, and would be more than happy to take you for a ride if you'd like.
I'll try to keep it below 70 for you. ;)

Well put, feel very confident in my 25...as with any boat there are risks...but with experience and seat time you learn the limitations of yourself and the hull...

I love my 25 AT........have I said this before? Not sure, but IMO I think i have.
