    Default OMC King Cobra strong enough for motor

    I am currently looking at buying a used boat from a friends friend kinda deal. I am only really interested because it comes with a very nice motor (blown 540 with a intercooled whipple supercharger) and would be a great family boat for Lake Tahoe. The boat is a 1990 30ft Advantage Victory that is in great shape (been sitting for 15 years) but it currently has an OMC King Cobra outdrive. I have been doing a lot of reading on these as the owners flat out told me these are not the best outdrives. I do not know the HP of the motor yet but I would assume it to be above 500HP and is obviously not an OMC powerplant.

    So my question is if I can buy this boat for lets say a really good deal how much would a complete replacement of a bravo 1 or other kind of outdrive that could handle this power cost?

    I am new to boats but not new to spending money LOL. Just trying to see if it would be worth my time if the price is right. I also have some pics of the boat and outdrive if that helps.

    thanks

    Default King Cobra

    If it is the cone clutch style it will probably hold up. If it is the early style that shifted in the lower gear case there were some issues with them not holding in gear. The transom hole is common and is the same as a Bravo style but I do not have any idea what a Bravo 2 set up would cost. None of the out drives are unbreakable especially if you jump waves at full throttle. I have seen some really shredded drives from doing that. Good luck

    Thanks for the reply, yes it is the cone style clutch model and I have read more on this. It does seem to be OK but I guess there are no parts for these as they only made them a few years. I will just put it all back together and see how she runs. Hopefully this will hold up for awhile as long as I don't jump it too much LOL.

    i know this doesn't answer your question about the drive handling the HP you have but back in the day (late 80s) OMC came out with the king cobra model and they were trying to change public opinion over the disastrous first gen cobra drive, they came to us at Advantage and wanted a record, any record. We built a banshee to try to capture the ETII klo record. With a mild, low manifold sbc and a king cobra drive with a nose cone, we set the record at 116+ mph with Harry's son Jeff handling the driving. The record still stands. But a better testament to their strength was entering the Mississippi race with the boat 2 years running. That race is 500 miles a day for 2 days up the mississippi. First year we got a dnf, next year won. We entered the Parker enduro and Harry flipped it in the first turn, tore off a sponson and the boat sank. We got it up, stripped it and sold it to a guy in Texas. We never had a moments trouble with the outdrive, and I never got back my aluminum carb scoop I put on the boat that Roger Weiman gave me in 1980.

    OMC published a very cool poster advertising the record with a picture of the boat, I wish I still had one.

    Thanks for story, stuff like this does help me get a better feel for what I have. I have heard some good stories of guys with decent HP running these with no issues, but of course plenty of bad ones. Just hoping it will last a few seasons.
