Concidering all the problems I've had trying to find parts for the KC outdrive - Da one link for connecting shift cable - Sooo totally OBSOLETE and I had to make it.....

I'm thinking of a change to a current outdrive - THAT I CAN FIND PARTS FOR !!!!

Been researching - Mercury Outdrives... Alpha - in my opinion - since I'm running over 400 HP is out..

Bravo 2 - seems to fit the NEED - cannot justify the Bravo III, expense, as impressive as it "looks" - the expense and bottom line performance has issues.

Question is - Gear ratios and then following changes "what prop" for my 22C? The new 502 BBC is estimated over 400hp - not justifying a dyno run - just want to get her in the water again!!! Sure..... I can use what I have - Yet - Yearning for best performance - it may have to be changed too..

I have found ratios for the OMC KC - What it means??

GMC 554 or 502 King Cobra after 1988 21:17 17:20 "


Question is ..... HOW to relate this info to Bravo's..... It's all GREEK to me.... trying to decide on Bravo 1 or 2??? Seams like .... Bravo 1 would be correct for the HP and boat??

Didn't like the corrison complaints about Merc outdrives - Yet... What can you do..

Also read the swap - is almost "pattern\alignment - painless - other than I would have to pull my engine AGAIN :(

Sure am glad.... I built a "back yard" hoist.


... isn't this the definative defination of a "back yard" mechanic !!!

Totally High School stuff - I love it....

Now that it is fixed by the time you break it you may sing a different tune, it will outlast most others. also unless you buy brand new you do not know what you are getting, you may just buy more head aches!

The KC gear ratio is 1.43:1

Don't know what the numbers are that you posted.

So, if you go Bravo I, you want the 1.5:1

That said, I'd keep the KC

just a thought Volvo did a KC/SX replacement/upgrade that might be worth a look.

The Bravo 2 is for bigger, slower boats. You'll want a Bravo 1 or one of the Bravo 1 variants. (XR, etc.).

Dollar for dollar it is hard to beat mercruiser. The parts are abundant and because they are, lots of competition and lower prices. They don't change much over time (if at all) so finding used drives and parts is easy.

I picked up 2 Bravo 1's a while back for $500 each serviced and ready to go. you'll need the transom assembly too, so that's an additional expense, but it won't set you back what most other drives will cost.

Not all kings are 1.43. Some are 1.42, some are 1.7ish.


I'd get that thing off your boat and ebay it. You'd be shocked how much they can fetch.



I had a King Cobra on my 22.....worst drive ever.


Where do you boat if you live in Oceanside? I'm thinking about moving back to SD....

"GMC 554 or 502 King Cobra after 1988 21:17 17:20"

this works out to a 1.45 / 1 gear ratio.
