    Default 25 Daytona with a black hawk drive???

    Hello, I was wondering if I could get some imput on this set up. I am looking at a 1998 Eliminator Daytona with a fuel injected 502 and a black hawk out drive. The owner said it is all stock from Eliminator and has 200hrs on it.I have heard of these drives on 22 daytonas ,but not 25's. I also heard that parts are hard to find if they break? Also being such a short drive are they hard to plane out?? Any feedback would be great! thinking of buying the boat this week!

    I had one of the original 22 with the blackhawk and a 502. Stock motor ran 95mph with great mid range and fuel mileage. It was hard to plane out with the 31's on it, took like 10 seconds. I could only fill the tanks 3/4 full or it would not plane but 3/4 tanks would last me 3 days on the water. It was a very efficient set up. The 22 was made specifically with the blackhawk drive application. It has a special notch in the transom to allow for the surface drive. I do not know if Eliminator made the same special notch mold for the 25. I have heard parts for the drive are hard to get now and props also. It is a shame, that drive had potential. What was nice was that you have zero sterring torque due to the counter rotating props. The 502 motors were good all the way up to 500 hours before they started seeing little problems so there is life in the motor. It should be a reliable set up for about 85mph (IMO). but there just is not a lot of stuff around for the drive in case something happens then you would have to replace with a bravo set up. If the price is right, might be worth giving it a run. You can always swap out a drive or add more HP to a motor.

    I would call Aaron over @ Max Machine works. Last time I was in their shop, they had a 26'ish daytona with a Blackhawk on it. I remember it had a big motor in it. Not sure how it worked, but the boat was in there for outdrive repairs. I am sure that Aaron could tell you the details.

    Last time I heard, finding replacement parts is extremely difficult. That is about the only downside to the drive. Efficient as can be & FAST!

    Want some real world info on that package? I put 200 hrs on a 25 with a 500efi and a BH drive.
    Excellent top end, midrange cruise and docking / trailering manners not so much.
    Boat gained 8mph by bolting on the BH but lost all ability to trim the bow up. Strictly relied on forward speed to carry the nose until over 70 when the drive would start to bite harder.
    Could be a bear to plane with any more than 2 adults and a kid on board if fueled heavy.
    Drive was perfectly reliable after converting to a HP vertical shaft. Never broke once.
    Cornering at mid range speeds ( 60 ) was a real treat. You did not let your attention slip. The hull would want to corner on the bow and with almost nothing in the water at the stern, had a real "on the edge" feeling. High speed was drifting more than cornering.
    Some definate trade offs but if you want the max top end and straight line ability and stability, an exceptional set up.

    Be aware! If this boat came from Eliminator with a Blackhawk drive, then it has a modified bottom; ALL 22 and 25 Dayton’s built with the Blackhawk drive had inserts placed in the mold to change the rocker in the outside sponsons. Because the Blackhawk is a surface drive, swinging two propellers, it creates lots of transom lift; to overcome the problem almost 2” of extra rocker was add to the bottom. Switching to a standard Bravo drive on a 22 or 25 Daytona designed for the Blackhawk can create handling problems and vice versa. Both the 22 and 25 inserts were done my Steve Donahue of MerCruiser Marine for testing of the Blackhawk drive and were used in all production Blackhawk applications. Steve had the only 25 Daytona with a Blackhawk drive and BlackTrac 2-speed transmission. With a stock 502 the boat would run in the mid 90’s. Also most people do not know there are two different decks and two different bottoms for the early 25 Daytona; both look allmost exactly the same. For the decks the difference is the location of the dash, the newer deck has the dashed moved forward several inches. The difference in bottoms is the number of notches forward of the transom, one has a singles notch about 9’ from the transom the newer bottom had the same notch and another about 2’ back. The later bottom had extra rocker add similar to the Blackhawk inserted bottom.
