I don't have an answer for your question, but I have a question for you, or maybe helpful info. How long have you had the 460 with the Cobra o/d ? I had a 24 ft Liberator with a Cobra outdrive. The first season I had it, I blew the outdrive 3 times. After the 3rd time, the dealer didn't want to honor my waranty ( I bought the boat used from a dealer and they gave me a 1 year warranty- pretty cool of them). It took my father and about 15 other bikers pulling up to the shop to "convince" them to honor the warranty. It turned out that the OMC Cobra ( stock ), couldn't handle the "stock" HP from the 460. After some upgrades, all problems were gone. I'm embarassed to say that I don't recall what the upgrades were, but do some research if you're not familiar with the Cobra. I hope this is helpful to you.

If it's an 88 KC drive, it will blow up repeatedly. I had a brand new 460 KC package in 88 on a light 22 ft pad bottom boat. Blew 13 drives in 139 hrs. Boat spent more time at the OMC factory than with me. They never did solve it's issues so I dumped it in 1990

This is my second boat with a Cobra drive..the first was a 92 Donzi classic with a 454/330 hp...Didnt have an issue..This one is a 460/340-345 hp..on a 89 donzi 22 classic..We will see..I am familiar with some upgrades, but definitely not an expert on them..just looking to see if someone has any idea if it would be better to change power.

thanks,
joe

I had a 88 Donzi Z25 with that drive and it was a heavy boat, could not keep it in the water because of rebuilding drives.

I still have a 1989 Baja Sport 226 with the OMC 460 and King Cobra Drive. I bought the boat new in 1990 and the only issue I had was the shift cable was defective. The factory replaced the shift cable and new drive. I still own the boat and never had another problem and still running strong. I might add everyting is still stock as came from the factory. I have no complaints with the package.

Baja,

I plan to keep it stock. I think with this package this little thing should run about 65-68 MPH...That should be enough for now..

Thanks,
Joe

There are two different King Cobra drives, in 89 or 90 the cone clutch drive came out and it was a great drive, just as strong as a stock Bravo. That was the same year OMC offered the 370hp (crankshaft) 454 KC. Most 460's had the older KC drive, but not all.

I had a 454 King Cobra (1990) and never had a lick of a problem with it.

Rex,

Yes, thats what I thought..My boat is an 89 22 donzi classic..I believe the engine produces 340/345 at crank...Seems to be ok.We will see...Just trying to figure out if I should change power or drives.

Thanks,
Joe

You can build the Ford to make good power, it just costs more than building a Chevy. If you want something a little different or are a Ford guy that may be up your alley.

Now as far as the drive, the lower unit may be the only different item on the new vs old drive. I dont believe the upper gears were the problem, and the cone clutch lower solved a lot of the durability problems and may bolt right on, I am not sure.

Finding parts will always be an issue too. When Volvo bought the OMC outdrive patents and machinery they never made the King Cobra so there are not as many of them around
