He's pretty close to me too, but I don't consider myself to be lucky....:eek:

[Raceman]

The place that I heard several of the racers have used with good results is in California if I remember right. John???????

As far as lettin' T Rex do it, I'd prefer to use somebody with power tools instead of a big hammer and chisel.

Think this is the place your referring to, has been endorsed by many racers turning extreme rpm.

[oldstv]

tell us what you find out.
Please!

[delawarerick]

Raceman isnt there someone down in Fl the mercury dealer I was working for used to send them to I think percision marine. Rick

Custom Crank --Iowa. Have run em to 10,000+ . :cool:

[Markus]

John Marles uses David's cranks for Mercs, Al Stoker uses them for OMCs and Hydrotec use them for Yamaha's "factory" rebuilds.

He did a Yamaha crank for me earlier this fall. I have not run the crank, but he is definitely good to deal with

After pacing for a month or so I decided to go with Marine Crankshaft in CA...Dave Eden..haven't received the crank back yet but was advised to go there by many race engine builders and a few other guys that have used them. This shop builds some bad ass stroker motor cranks that some are running in Pro Gas. I'll let you know when I get it back.

I would like to see how they weld a journal, machine it, finish grind it, and case harden it as a fresh forging and retain the integrity of a forging. Do these rebuild guys warranty the crank, AS WELL AS THE PARTS THEY DESTROY upon failure????

[Liqui-Fly]

The guy in CA uses magic because his stuff is so much better than everyone else's. Do you warrantee your work on high performance outboards??

David

[BRENT GILL]

OCC was the one that developed the process
and have been rebuilding them for almost 20 years.
The welding is done by a computor
The shafts are magna-fluxed , shot peened,
and rehardened.

Their ad says they work great at 8000k.

In most cases you can find a good used crank
at around the same price by the time you ship both ways.

Fishing motor, or a big offshore boat 8k or below - No problem
10k - motor-- Why would you chance it. Blocks cost too much!

My 2 cents

[Liqui-Fly]

A good used crank that someone else sent to OCC and is selling as a perfect crank. You pretty much take your chances anywhere other than brand new.

David

[Raceman]

I talked to David at Marine Crankshaft. He says about 375 and 10 day turnaround.

As for the "why risk it" part............... it's the crank from my F1 V8 project and so far I haven't had any luck finding a virgin replacement.

[Markus]

Come on Bill, if Dave's cranks are good enough for Yamaha Motor Corporation, they should certainly be good enough for any OMC. :D :D :D

[BRENT GILL]

I under stand for an F-1!

David , just so you know,
if someone has a crank for
sale and you don't know if
its rebuilt, just look on the
top counter weight and there
will be a # ingraved. Thats for
the warrenty information.

Brent

[Liqui-Fly]

I was wondering if they did something like that. I've got my fingers crossed...don't plan to run this motor over 8 grand. At 8 but not over.

David

[espen]

I have got cranks rebuilt buy David . As I could see they where perfect....He clamed he could make stroker cranks , or shorter stroke for a 3l .
There where one guy here posting ,claming to just grind the cranck and use oversize bearings and not loose much of the crancks strength compared to a welded. John says he dont repair nr 1 on the cranks when spinning high rpm ,just the lower ones .

Found the link :http://www.neecaprecisions.com/
seek for
neecapr on the board or novalves and there are some interesting info.

[Bill Gohr]

use alot of rebuilt cranks, and on fishing motors it may be OK. I myself will always go for the used piece and will not buy a used assembly that has been polished, I want to see it as it came out or I don't want it. I mentioned the warranty thing because I know people who have had unexplained failures, possibly being from the repair of a journal and the crank company was nice enough to replace the crank. What about the block. rod, piston and head?

When you weld a journal what happens to the areas adjacent to the journal? Is the heat treat as even between the welded area and the forging as an undamaged forging? Ask a metalergist. Computer welding gives you a nice even weld and magnafluxing just checks for imperfections, doesn't make something perfect.

I'm not saying you can't repair a journal and gave good luck with it under alot of applications. The misconception is that the crank is as good as what you had, and it's not and can't be.

Liqui-fly, of course I warranty what I do. If I repair a STOCK as built by Merc, Hi Perf engine. If it is Modified I won't but neither does Merc or OMC.

[Liqui-Fly]

You're making me sick to my stomach. The little scmof on my journal is getting fixed and is going itno a fairly modified motor that I'm spending my bottle and can money on. I guess we'll see what happens.

David

[Bill Gohr]

now theres something I've heard from more than one crank guy. Why won't they repair #1, I think I just told ya......

[Liqui-Fly]

#5

[BenKeith]

Raceman,

I just got through asking the same thing. Stoker refered me to David at Marine Crank. Stoker says he 's used Davids cranks in his drag motors turning over 9,000 and never had a problem. Sounds like he does a pretty good job to me.

[Liqui-Fly]

Yeah but I think those are new cranks...not repaired.

[Bill Gohr]

I wasn't aware Yamaha buys rebuilt cranks from them.

[Raceman]

My F1 V8 probably won't see a lot of hard use anyway, although I do want to hook it up to a dyno and verify (:D yeah right) some of the wild horsepower claims that've been posted here for em.

[Markus]

Bill, this is how it works. Please note that only items 18-22 deal with Dave's work in relation to Yamaha factory rebuilds. The rest is meant as education to those of you who work on your engines yourselves. ;)

1. After running his engine at WOT for 3000 hours, Yamaha owner gets some junk in one carburator and burns the #3 piston

2. Yamaha owner tows his bass boat to the dealership where he bought his rig 10 years ago and tells the guy behind the counter that the engine suddenly lost 1100 rpm at WOT

3. Guy behind counter + Yamaha owner goes out to check out boat. Guy behind counter notices that he has not seen the engine since he sold it 10 years ago and asks what kind of maintenance the Yamaha owner performs

4. Yamaha owner responds that since he is using the boat year round, he does not think it is necessary to winterize it and stuff

5. Dealer looks at engine and asks whether Yamaha owner has changed impeller or gear lube since he bought the engine

6. Yamaha owner answers no

7. Dealer takes out plugs and notices that the plugs are the same NGK B8HS-10s that came in the engine from the factory and that there is melted aluminum on plug #3

8. Dealer says that he will have to tear down the engine to find out what is wrong and tells Yamaha owner to back the trailer into the yard behind the shop

9. Dealer tells Yamaha owner that he is really busy right now, but that Yamaha owner could call back in a week or two

10. Yamaha owner calls back in a week, but dealer has not yet torn down the engine

11. Dealer takes off both heads after another couple of days and sees that piston #3 is burnt. Other than that, engine looks fine

12. Yamaha owner calls back again. Dealer says that a new powerhead is required. However, since a new powerhead is 8000 dollars, Dealer recommends a Yamaha factory rebuilt powerhead for 4000 dollars. In addition, Dealer says, Yamaha owner is looking at another 1000 dollars in various parts, labor and shipping of the core and powerhead

13. Yamaha owner says he needs to think about it considering that it is a 10 year old engine. Dealer says that he understands that, and the he can give Yamaha owner a really good deal on a new 30000 dollar Skeeter bass boat considering the trade-in and all.

14. Yamaha owner discusses new bass boat with wife who does not fully understand the need. Yamaha owner also Googles for "Yamaha rebuilt powerhead" and sees several offerings for 2500 dollars and less.

15. Yamaha owner calls Dealer and says that he would like to keep what he has since the boat has become like a buddy. Yamaha owner also asks why Dealer's powerhead is 1500 dollars more expensive than what he say on the web.

16. Dealer says that Yamaha rebuilt is better, using factory parts. Dealer has sold Yamaha since 1987 and would never trust anything else.

17. Yamaha owner says OK, remembering what happened to the engines of hiss bass fishing buddies who bought OMCs at the same time he bought his Yamaha, and tells dealer to go ahead with the work

18. Dealer orders rebuilt powerhead from Yamaha Motor Corporation USA.

19. Dealer strips powerhead and ships it off as core

20. Official Yamaha Factory Rebuild Center Hydro Tec gets order for rebuilt powerhead for 1993 Yamaha Pro-V 200

21. Remanufacturing shop at Hydro Tec has just put one of Dave's rebuilt cranks (big upper type) into a 1991-1995 style Pro-V 200 block with a new Yamaha sleeve and 2 new Yamaha pistons

22. Hydro Tec ships Pro-V 200 powerhead to Dealer

23. Dealer receives powerhead and calls Yamaha owner and says that power head has arrived and that it looks great. Dealer says that to save time, he has already changed impeller and gear lube and cleaned out the carbs. Dealer says there was some junk in carb #3 that caused the problem.

24. Dealer dresses powerhead and puts it on midsection and runs engine on hose to make sure it runs good.

25. Dealer does the numbers and calls owner to say boat is ready.

26. Yamaha owner says Great! How much do I need to pay?

27. Dealer says, well it actually got a bit more expensive than I expected, but when I say 5000, I try to keep my promise

28. Yamaha owner goes to dealer with 5000 dollar check

29. Yamaha owner goes home with boat and a hand-written receipt slip with the items Rebuilt powerhead, gasket kit, impeller, gear lube, BR8HS-10 spark plugs, shipping and labor. It is all summed down to 5361.24 dollars, but crossed out and rounded to 5000.

30. Yamaha owner can go fishing again

[Markus]

From what I have understood from John Marles (please chip in, John, if I am wrong), but John and Al put Dave's cranks in 9000 rpm engines.

Further, I think the journal #1 issue only applies to V6 Mercs.

[Bill Gohr]

The Yamaha owner bought a rebuilt powerhead from Hydro Tech not Yamaha. If that powerhead has a problem and you call Yamaha's warranty dept. they'll tell you to call Hydro-Tech because you bought the unit from them.

If Hydro-Tech uses cranks from this rebuilder thats their decision. And if they do I'm sure Wayne tested the product and is satisfied with the outcome. Wayne builds a very good product and has an extremely good reputation, I'm sure he wouldn't chance that on something he wasn't comfortable with.

As I said in my earlier post, a repaired crank may be OK in a fishing boat application.

As well in some cases as in the begining of this thread you may be forced into rebuilding a crank because it is unavailable. If I was in Racemans shoes and couldn't come up with a crank I would probabaly have it repaired. Till then I'll just stick with a good used one.

[Russ]

Very good question in your earlier post on the 1st page! I've had a long standing position concerning re-manufactured or stroked cranks for that matter. If there is more info out there addressing what these processes being used are, would sure like to hear about them...

[Dave S]

I have seen welded cranks go bad in a years time. I can find a good used crank for the price of the welded crank. If you got a rare part or no other choice then ok.

Thats the place. They are as good as NEW. Al Stoker will also vouch for David.

[Raceman]

John, that makes me feel a lot better. My V8 crank is on the way there now.

[us1]

He is really good. Sorry I didn't see the post earlier, I dont know how I missed it. Tell him I sent you, you might get a better deal.

[Markus]

John,

I have already tried dropping both your name and Al's name, but the price was the same. :D :D

[Dave S]

The Cranks I saw broke was 10 years ago, the guy you are talkin about is not the ones who did them. Any one want some old cranks for cores ?? Fissn motor cranks.;)
