Crash Boxes ... Pros & Cons
 

CRASH BOXES PROS & CONS ??????? Lets hear em :coolcowboy:
thanks in Advance :drink:

Only + if u got used to them !!!!!!!!!!!!

Last longer and get more HP to the prop.

I have had them two weeks now, really not that hard getting used to, Mercury power and the way they idle makes that happen. Only big disadvantage I have seen is trying to tie up in a congested area with a wind.

Thanks Mac i'm thinkin we may have probs docking and manuevering around the marina :eek: At LOTO@ Shooters 2 years back helped a 47 Outerlimits orange with Ostrich leather and had boxes and some probs docking and crashed the dock .:mad:

If you buy these SCS shiftable's you shouldn't have any worries...........These are what I bought for my rig. :drink:


Check out this link for a pair in Michigan.
Price new and it will shock you :drink:

Jon

THE NAME TELLS YOU ALOT. "CRASHBOX"

didn't Jim Lee have some made by Big Yellow Cat/Tyson?

Sorry for the ignorance, whats a crash box?

OH CHIT :eek::poopoo:

I thought Jimmy & Tyson were doing the 2 speed 2000 hp transmissions but i may be wrong :drink::bigbird:

TRANS CANT SHIFT WITH MOTOR RUNNING. GOTTA BE FAST WITH YOUR HANDS. RU SONIC JOHNNY FROM GROVERS?

Heres the ticket Bill!

I had them in one of my Sutphens.

Good batteries + Good starters = No problem.

Just takes a little practice.

Thanks BIG Daddy :drink:Some very Trick hardware :coolcowboy:

I am Johnny with the Sonic from Grovers.......I see the confusion though........... you heading out to NY this year El Indio.......Johnny D..............

You can probably buy Earls whole shop for what they want for those shiftable crashboxes. Just buy some stock in Huber and keep ordering them.

I think you are on the right track all ready.

Jim and Tyson are doing the fine tuning on the 2 speed trannies in Freedom. I was in Freedom on Memorial Day weekend and they work great. Jim is very excited about them. They are just awesome around the docks with the lower gear. He is able to place that big Skater exactly where he wants too and if Jim can't break them, I do not think anyone will be able to. Talk to Jim about them and he can tell you exactly where they stand on them. I have been in Rare Breed's new ride with the crash boxes the last two weekends. They have not been a major problem, but you always have to plan ahead with them because it just takes longer to react when you have too.

Send me the 72C you gots ,the boyz want to open one up and have a look see:eek::drink:

You want one with a tail or one with a driveline? The driveline one aint sheap, but if you want a regular one, I can probably arrange something. The only difference is the housing. Guts are the same.

Lets see what happens in the morn BIG Daddy , i have a call into Randy @ Marine drive he may have 1 on the shelf to get us back out testing & tuning this weekend .

My drive line is only good for about 800 hp. It's a huber 940 I think, but I would have to check the receipt from when I had it built.

Sounds like a good candidate for upgrades and improvements :drink:

Coan Engineering makes a 2 speed transmission that is rated for up to 2000 Horsepower. There number is 765-456-3957 they are in Kokomo IN. We have tested them in my 32 Skater and they are working good.

Thanks BIG Daddy will give them a call this morn :drink: are the Coan the Kieth Eickert ones that were in Powerboat ???

ZERO DRAG TRANSMISSION

Since 1990, SCS has produced a Crashbox that has stood up to the Blown Motors when the "Daytona Style" could not. In 1998, the unit was modified by Mike Sage, owner of SCS, to stop the internal gearing from turning in the Forward Position. Net gain was about 4 MPH on virtually every catamaran when they replaced the Standard SCS Crashbox or the Daytona. In the fall of 1999, Mercury Racing dropped the Daytona crashbox and now buys SCS Zero's for all their crashbox needs! It is available with 1480/1510 Large Flange or 1350/1410 Small Flange Outputs. Custom Inputs available for Turbine applications with brake rotor hubs. SCS also offers a clutched Zero Crashbox to replace 72c when it becomes the weak link!

SWEEEEEEEEEEEEEEEET :drink::coolcowboy:

Yes, Coan's are the one's that Keith helped with. They just did an article in the Poker Runs magazine last month. If you give Keith a call he could tell you more about the transmission.Thanks

YOU GOTTER. CYA AT DANTES.

Yes we built some bad AZZ transmissions. SPEED SHIFT TRANSMISSIONS. I test what we build with a 46 skater with 1300 hp per side. Been there done that with Bam and SCS. I boat a lot and saw a need for Bad azz transmissions. I will have them in my boat FREEDOM US1 in jax and will race with them to BIMINI and back next weekend.

You are right and we will be ready to release the first sets to whoever wants them after the jax poker run.

Thanks Stan you are right!! We will let people know what we have during the JAX poker run. We have a winner!!!

If you want some transmissions that are proven to take the chit give me a call. Jim Lee 316 648 2414. You know how I run a 46 Skater!!!!

Now, I'm wanting some BAD ASS transmissions!!!! will these be the ones??:kiss:

Dang right!!! We can look at your set up and fix you up! Love to have you as a customer. That's why we have been testing them so long. I will be selling them to my friends and wanted to work out any weak spots!!! Come to jax man!!! You don't need a boat.

Yo Big Daddy.

Did ya ever talk to Tyson on the overdrive deal?

Turbines and TwoSpeeds thats what I,m talking about:drink:

I always thought it would be a great idea to run two speed transmissions on any boat.

I looked at the transmissions on the Coan website and realized that they might be high performance powerglide transmissions adapted to fit marine applications.

Stock Powerglide Case

http://www.coanracing.com/Imgs/COA-1...A-12837A_2.jpg

If that is the basis of their two speed transmissions, Coan Engineering has hit on an excellent solution. Drag racers have been using Powerglides for 50 years and virtually bulletproof components have been developed. There have been custom shiftable transmissions out there, but nothing with the track record of the Powerglide.

I am sure they are not cheap, but by adapting the high horsepower powerglide for marine applications, they could put shiftable transmissions into the hands of a lot more performance boaters.

Sweeeeeeeeeeeeeeeeeeeeeeeet :eek::drink:
