525 Whipple
 

Has anybody tried the newer whipple kit on there 525efi using the 555 pcm? Just wondering how they are working out? Will the xr drive hold if you drove it nice to plane and using common since?

Our first customer that we did the testing on, has well over 250 hours on his Conquest deck boat, still the stock XR, still the stock everything but the SC.

My buddy has had one on his Cobra for several years and has not had any problems with anything on it.

Sweet setup but the XR bearly holds up with stock power! You will love the extra power and performance but hate breaking drives. Plan on buying Arneson, scx, scx-4. I run procharged 500efis and wear out the XR gears in my imco sc drives every summer.

That really depends on the boat and the one running the throttle. Our first customer with the later setup has his on a deck boat, runs 97mph, has never hurt the drive and by years end will have 300 hours with the SC. There's certain boats that break them consistently, but there are far more than don't have problems. Most that break them are dual motor boats with very high X-dimensions.

Heavy boat, ocean....issues,,,,Light boat, no swells, Prolly OK

No offense here, but your Baja is part of the problem. Not exactly efficient.

Would like to go with whipple on a 29 v hull single xr drive but have heard a lot of problems with the xr's. Never felt my 525 performs like it should, so trying to decided. Boating on inland lakes, easing into throttle, keeping drive in water maybe it would last. Sure like to have the extra power, but not always working on it either.

We have a twin engine boat that has whippled 525s and has run all summer with no issue's and he has XR's

And he's not exactly easy on the sticks....

So why do 2 of my friends 37OL (that run slower then my Baja) break them?

Do some research. There are so many broken bravo thread on OSO its ridiculous. STOCK 525 288 Sunsation MCOB just broke one at 80hrs inland lake family boating. 29 laveycraft also stock low hours.

Nothing against the whipple. Its not the whipple, the procharger, the hardin marine turbo, N/A, etc, its the plain fact of MORE POWER will Destroy a XR. FACT.

There is no magic to it. NO secret way to drive. No magic oil. XR drives break every day. There is a reason there are so many shops that rebuild them.

YES supercharging your boat would be great BUT only if you are aware of the upgraded NEEDED to the drive.

Not fair to not warn or prepare someone.

Not at all. He runs it.

I need 2 of the 525 kits please!!!

Formula's and Cig's dont break them either....right ?;)

I've had some customers break 5 in one year, one on a Active thunder, dual motor, but I can tell you almost all our customers have stock XR's that live. We have thousands of customers that don't post on OSO and there are many with no problems.

There may be no magic, but again, it comes down to wetted surface/resistance of the boat, X dimension, prop style, speed, boating conditions and the main thing, the one controlling the sticks. I've never broken an XR or Imco SC and I've driven some pretty stupid power/drive combo's.

spend the money on the set up, or on buying new uppers.... there are quite a few variables that are driver related. i can attest that the swept uppers, honed out and changing shafts caused my merc 600 efi sci to live just fine in 100 hr increments on my 39 tg. changed the oil every 20 hrs, with the engine oil change, and never ran a constant speed for an excessive amount of time, causing the fluid to always be moving around in the drive. gears looked fine at 100 hrs. insurance policy to replace the gears in the off-season vs. wondering if it'll last another season etc...

and yes, they are a flawed design imo. very surprised they mated them to the 600 and the new 565. but, i must say, i am less of a fan of the nxt, which is why i went with the 600 vs 700 pkg. too many reasons not to buy the nxt. again, just my opinion. not bashing.
