Well we have shelled our last drive and are considering installing IMCOS new SCX drives. The boat is an 05' Ex with Tyler Crockett Whipple Charged 525's. They dynod @ 808 a side. Has anyone installed the new IMCO's on a 42 ftn? How do they like them? Are they running extension boxes? Our current setup is XR's with IMCO 2" shorties and 1" spacers....spinning 33" Hydromotive P5+'s. This prop combo hasnt been the best so we will for sure change when we install new drives. Any input on this would be GREATLY appreciated. Thank you.

It kind of defeats the purpose of upgrading your power if you give a lot of it back with a power eating drive.

Some people are having success running the Teague drives.

Yeah, I too am interested in seeing how they work on a 42 with 800+ HP.

I would think your setup would live longer with a 1.35 ratio and thinned 4 blades.

How many hours are you guys getting out of your bravo's now before they pop?

Is a week or two very long???? Seems to happen between 3/4 and WOT...even with gradual stick movement. We have shelled both port and Stbd motors this summer.

I DO NOT want to lose any speed. Hmmmm, what to do??? My understanding is that the Teague drive is nothing but a Teague case with XR guts.....I may check into Max Works.

Whats letting go....Gear teeth? Shafts?
I too have broken many Bravo's, IMCO SC's, and a few Bmax's till I got the Gearing and Prop pitch right.

Wonder if you have an allignment issue - that''s too soon to be breaking them.

As far as the teagues go it's my understanding that they do more then just assemble the parts - I've heard something about them tweeking them to better tolerances. I know they at least put a warranty behind their product with the Ilmor 710 - that's more than IMCO will do I think. I've heard great claims about max machine works, but also stories about people dumping huge money into their drives and breaking them the first time out - with no warranty.

sucks - anything over 650 hp or so is in no-man's land. Unless you want to spend huge money on a nxt or 6 drive.


What kind of speeds are you seeing with those whipples - before and after install? Have the motors been reliable since you installed them?

Boat is a consistent 100MPH boat....with factory 525's it was 86MPH. We still do not have it proped right though. I WOULD NOT reccomend the Whipple setup. It has been nothing but problematic from the onset.....despite being installed by a "Whipple Authorized Installer". Had more issues than can be typed on this forum prior to sending up to Tyler Crockett. He finally got it right.
We had to change to boat over to open cooling to keep it from overheating...tried EVERTHING else before doing that. Next time I will either go 1075's or Sterlings, or maybe a Teague motor or have Tyler Build me one. NEVER will I go the "Bolt on Horsepower" route. Whipple is very misleading on their product and their customer support is the worst I have ever experienced.

I have pretty much come to the conclusion that I will never again buy a boat with the intention of modifying it to make it go faster (excluding prop changes). It takes too much time, energy, money, and headaches. Next time I will buy something that already goes the speed that I want.
