omc out drive
 

Guy's, I took out and outdrive (cobra) on our 32 Fourwinns express Friday, of course we were heading down to Fells Point in Baltimore for the festival. Made it about 25 min out from Great Oak and BAM! I need one for a 5.7 standard rotation. If anyone knows of a good deal in the upper chesapeake bay (chesapeake city) please let me know.
We took the Scarab down Sat and it ran like a CHAMP!

Find a King Cobra to replace it with and boat happily ever after .

Deep.I have thought about changing over. I have twin 5.7's. Can I run a king with a plain cobra? I think the gearing is the same on V8's .Thanks

I ran a King lower with the Cobra upper . I forget what year King will mate up . I had a 1988 model . Built a 383 stroker and became a Cobra killer . I have never heard of a King being broken . Only problem was the King lower is longer than the Cobra and with the horsepower the boat wanted to ride on the cav plate . No steering at wfo . Raised the x 1 7/8" and it handled beautifully after that . I bought mine from I think Bayside Marine in Ca. brand new cheaper than I could buy a plain Cobra around here . I hope this helps you , let me know what you find out . I'll dig around , I may still have the sales slips .

Today is your lucky day , I found the sales slip .

Part# 438058 g/case 87/89 King List price $2064.75 My price $1548.56 This was on 7/16/1996 :ernaehrung004:

Thanks Deep. I'll look into it tomorrow. I may have a found a complete drive for $800.00. We'll see what happens.......

If that is just a Cobra beware of the dog gears , that is the weak link . My stroker also put the forward gear in the lower unit out the side of the case . :poopoo:

craigslist. 2 on kent island. 750. i dunno if it is for both or not. a couple up by me in s. jersey for 300 each, didn't say what motor or ratio. the kent island ones were 305 engines. means 1.5's i am pretty sure...

A real King Cobra is now pretty rare and shifts in the upper...A Cobra shifts in the lower........Curious as to how you did what you said....Kings do break and you will have a lot of trouble getting parts. Some of the later King Cobras behind 460 fords were actually just cobras with "king" in their name

I posted the part # . Do a little research . You should rethink your statement about King Cobras and 460 Fords . A standard Cobra would have died as soon a you throttled up . Here , this will answer all your questions as to me doing what I said I did and also parts availability along with durability !! http://www.allamericandriveservice.com/OMCCobra.html

Even if the parts in the "baby king" lower are supposed to be a little bigger ,It is still a clutch dog style lower ...and the same barely adequate (for high load) upper as a standard cobra.My point on King Cobra's (cone clutch) is it's getting hard to find anything for them and they have a different transom assembly .I still call the "baby king" just a cobra.If you had good luck with one ,good .I've had too much power in front of an alpha before and it lived because I knew what I had.

I put 470hp to mine and never broke it . I never said A king Cobra is the best there is but it is strong to a point . My suggestion to the op was to get him longer life and more dependability with what he has . Your purpose here seems to be to give me a hard time even after I proved to you that I in fact did what I said I did . The Baby King lower is much much stronger than a regular Cobra as per America Drive Service and myself being I have actually bought one and put it to the test . What have you done besides run your fockin mouth .

I'm home after a long day and having a drink .I was working on the cobra drives and baby "king"cobra's when they were new. Not giving you a hard time just stating what I know. If you want to argue ,we can ...I'd rather argue face to face
I'm glad you had good luck with your omc

I am happy you would rather be civil . While you are relaxing with your drink visit this site again and scroll down to what they have printed out in red . http://www.allamericandriveservice.com/OMCCobra.html All American Drive Service is well respected here on OSO and what they chose to put in print can also be taken seriously . Lets be perfectly clear , I am not an OMC fan because of the chit I went through with my drive . Now I tend to tell everyone " If it's not black take it back " Because of my experience with this drive I do however try my best to help those that I can that have OMC issues .

I have done a lot of work on cobra drives over the years & for stock use I wouldn't kick one off the back of a boat. For high performance use I personally would go with merc, just because of cheaper parts availability. My 4 wins had a 5.7 liter gm with a king cobra & that boat was a battle wagon!! It is still on the water to this day. My only advice would be to read the book, use gasket sealer on everything, and make sure to vacuum AND pressure test or it will leak. Good luck. Randy

I don't think I ever said I'd kick a properly functioning one off the boat. If I liked the boat and needed to spend real dollars on the cobra, I'd start considering an alpha transom assembly and drive.The transom cut is the same.
FWIW after omc upgraded the dogs,they worked all right for stockish power. It's just getting hard to find the old omc stuff at anything close to reasonable...Alpha parts are everywhere and cheap.
Obviously if you have a motor with good power,, neither of the above will stand the abuse.. Trade in the boat or go Bravo style stuff. Still the same transom cut, although you have to drill two more holes for mounting

Hey guys. I found a good drive at Harbor North marina right around the corner from my house. I had them go through it and reseal it. Looks like a new drive now. For $650 I got the drive and $350.00 to pull it apart, inspect and reseal. My game plan it take off the lower drive (of the blown drive),replace it with a good lower that I have, check the top drive, reseal and have a spare drive for the next time. I'll keep you posted.
I have had these drives on the boat for about 10 years now, change the fluid every year. I SHOULD have had them pressure/vac checked as part of my maintance and I didn't. Lesson learned........
