I really need some help. King cobra 460 kinda problems

[HT32BSX115]

Ok then lets look at this one now....

If that picture is of the drive you're considering, what you're calling the "raw water pump" looks like the shift actuator housing.

We cannot post links to competitor sites but I think I can post a link to BRP since they don't sell any parts directly..... http://epc.brp.com
Look at your year model drive exploded diagram and compare to 95 and newer OMC/SX drives. There's a pretty significant difference. ALL OMC/VP SX drives 1995-ON use an engine driven raw water pump. The "housing" on the SX where the raw water pump was on earlier drives is the shift actuator housing.

I also don't think ANY interim [90-93] OMC Cone-Clutch drive had "Volvo Penta" written anywhere on it.

 

[bruceb58]

Mine is a 91...with the 460

There was no 460 in 1991. Yours is a 1990. Doesn't matter what the year of your boat is.

 

[bruceb58]

3. The Joint Venture OMC/Volvo Penta Cone-Clutch (raw water pump on the engine) happened around 1993.5-1994 (to liquidation of the company in approx 1998) Like the one in the above picture you posted.

Rick,

The big block motors didn't get the SX type drives until 96. Before that(including 95), the old dog clutch king was still being used.That 3868211 drive that he showed was a 95 from my searches.

:thumb: :thumb: YUP! Just looked again at the BRP site. 96 appears to be the first year for the SX on the back of a 454.

The following is last year for the Interim drive [+454] (raw pump on the drive)

744DPHUB 1995
74FEPHUB 1995
Neither of the above are SX's and they are not "DOGS" either............... I suspect they would bolt to the back of a 90 Interim gimbal, but I wouldn't buy one unless I could check it first!!

AND correct. 1990 was the ONLY year for the interim drive + the 460.....(no 460 after 90) but according to BRP, the Interim drives were used on the 7.4 and 8.2 until 95

Just did a part number inspection and it appears that the upper gear housing in 1990 was the same for the 460 and 454 and 5.7L . OMC 0986192

(but not the 90- 5.8L because it was a "Dog")

The interim drive housing part numbers are not the same for housings newer than 90. (doesn't mean they won't "fit" but again, I wouldn't buy one unless I could check it first)

 

[bruceb58]

I checked out the yoke too between the 460 and Chevy 7.4L and they appear to be identical as well.

 

[HT32BSX115]

Still don't think any SX drive will bolt to an OMC Cone Clutch (NON-SX) transom mount.

It may be possible to install an SX pivot housing in a NON-SX transom mount though. I seem to remember DonS forwarding me a how-to where it was done with a Dog clutch transom.

I still think his best bet would be to get an SX drive and transom mount along with a Volvo dressed 454. But only if he can get that SX drive "for a song".

And for a 28ft boat, I wouldn't consider anything smaller than a 454.

 

[bruceb58]

The shift cable and water intake come in on opposites sides between the SX and KingCobra clutch models.

Not even going to guess if the trim Rams would even move over to the right spot.

Is she worth it?

The interior is mint... So is the 460.

It's still my understanding that the a VP SX will not work on the back of an interim transom mount. Not even close

The boat is a nice looking one! If the 460 is a good one and it still runs good, pull it and sell it.

Remove the transom mount, Y-pipe, trim pump, any other accessories and sell them piece by piece.

If the drive is damaged, sell it for parts. There are other poor souls out there in radio land that have similar problems.

Start looking for a complete Mercruiser or Volvo "Big-Block" engine and drive. lean towards either a Bravo III or a Duo-Prop if you find a Volvo.

Depending on what's wrong with your drive, there are companies out there that can actually rebuild your current drive and/or they even have an exchange price (Your drive actually has a "core" value.....albeit not much)

This would be my last resort choice considering the show-stopper parts on that 460 and the drive that have no replacement.


Ok, more "stuff"

I remembered DonS telling me about a conversion from a 7.5L King Cobra (like I had) to a Volvo Penta DPS using a transom shield kit and a raw water pump for a 5.7L engine.

The thread is here for you to read about. http://forums.iboats.com/forum/engin...cobra-outdrive

I was told this "kit" would NOT work with an early OMC (interim) Cone-clutch drive.



Ok....here's more on the differences.....

Ya i have read all of Dons posts and yours on every thread ...you guys know your stuff. But hey i have found another drive i need help figuring out. Is this a cone?

 

[Twcash]

See...now i do want to do the conversion at some point but would like to do that when i have more time and money. My drive is good except for the bearing carrier. That is not going to be easy to find. So im thinking if the drive in the pics above is a cone clutch then i can pull the carrier and put my lower back together and keep the rest for parts.

 

[Twcash]

The seller of the drive is saying it needs new upper seals. This is clear in the picture with oil on the floor, i have my drive in the shop with a new lower seal kit waiting for a carrier. Was told my lower case was shot so i also hunted down another lower case to replace mine. They told me my gears are in great shape( not surprising) so i would have 2 lower cases and parts for the upper from this new find. I also have found several 460's for sale. My 460 like i said is in great shape and it will push my boat well enough.

 

[Twcash]

Im pretty sure that drive is a cone clutch judging by the scag. It starts at the back of the case and goes to the prop edge.

Those drives are fairly easy to identify but the Skeg is not much of a feature to go by.

If the drive has a raw water pump on the back, and does not have a "flat" top, it will be a cone-clutch model.

Here's a great side by side comparison http://www.allamericandriveservice.com/OMCCobra.html

You can identify it as a "Cone" by looking at the top of the "upper". If it as a "hump" and the raw water pump is on the back of the drive, it is indeed a "cone".

Now, is it a Cone that will work with a 460? I cannot tell you that.

OTOH,

My drive is good except for the bearing carrier.

If you're looking for a "Bearing Carrier" Are we talking about "0913869 HOUSING, Propeller shaft" ??

If so, that part OMC 093869 (referring to http://epc.brp.com/) is common to the following drives.

(I found this info by using Google --> "OMC 0913869" then going to a link that listed all the OMC Eng/Sterndrive models that used the #0913869 bearing carrier) There weren't very many

PRODUCT OBSOLETE
This OMC 0913869 L/P is used on these models and components:

1990 574APEPWS LOWER GEARCASE
1990 574BPEPWS LOWER GEARCASE
1990 744APEPWS LOWER GEARCASE
1990 754APEPWS LOWER GEARCASE
1991 574APERGD LOWER GEARCASE
1991 574BPERGD LOWER GEARCASE
1991 744APERGD LOWER GEARCASE
1991 744APERGF LOWER GEARCASE
1991 744BPERGD LOWER GEARCASE
1990 574APEPWS LOWER GEARCASE
1990 574BPEPWS LOWER GEARCASE
1991 574APERGD LOWER GEARCASE
1991 574BPERGD LOWER GEARCASE

SO if the drive you have in your picture was one of the above, the bearing carrier would work in your drive.

If you cannot identify what that drive came from. The only way to use it would be to pull it apart and look for the part number. OMC put their part numbers on a great many parts.

If you can find someone that has a list of drive model numbers that would do it too!

Sorry I can't be of more help.

 

[Twcash]

Wow...so basically2 years to work with. Thats not good.

 

[HT32BSX115]

Wow...so basically2 years to work with. Thats not good.

Yeah. it's not good.....they only made that style of drive for a couple of years. They're pretty rare, and there's virtually no spare parts for them other than those that were left over when OMC went out of business and parts from junked drives etc.....for a while, there were NO raw water pump impellers available from anyone.

I think Sierra might be doing them now (don't know who makes them) . It's incomprehensible that they didn't use an off-the-shelf impeller for them. The impellers are literally unique to the cone-clutch Cobra drive.

Many people had to fab up mounts to install an engine driven pump like the later Volvos because they could NOT find something as simple as a replacement impeller!!

. This is why most of us here will recommend people stay far away from this model and if you do decide to get one, it's best to buy it "as-is" parts only, etc....... where the engine and drive is concerned......Problem is there's still a LOT of them out there in good running order. Unsuspecting people buy them thinking they're getting a sweet deal (that is until they try to get certain parts for them and find out there's none to be had!!)

If you get that drive fixed where you can operate it, treat it VERY gently! Look for a replacement engine and drive.............. and then sell all the OMC stuff to someone else. There's still enough people out there with them looking either replacements or parts to fix theirs......
