    HOW FAST IS YOUR CHECKMATE? EVERYONE!

    I have a 2400 long deck / 300R (2020 and the 2nd last boat built in Bucyrus). Initially I could only get about 72 mph around 6200 rpm with a 24P Bravo FS. Once I redid my poor break-in and had #7 injector harness wire changed the boat picked up. Now the weather helped for sure since it was about...

    What prop for my set up?

    If I had to guess I would think that a 30P is going to be a bit too much pitch but you never know until you try. The difference between 1.36 and 1.65 is about 20%, so if you turned a 22P x 1.20 = 26.4P with a 1.36 drive, then if you switched the drive ratio to 1.65 it would theoretically turn a...

    What prop for my set up?

    I am not 100% certain, but I think you can use the left hand 28P prop for a test by running the control lever in reverse, provided the cable produces full throttle in both the forward and reverse position but I would check with someone that knows more about Bravo Drives than me on that. I think...

    What prop for my set up?

    I used to own a 230SX Stingray with a 496 Mag and Bravo 1 drive. That engine was rated at 375 HP. You could also order a 496 Mag HO which was rated at 425 HP. If you ordered the 425HP version, Mercury only sold it with an XR drive. Anytime the HP went much over 400 HP, Mercury usually sold them...

    What prop for my set up?

    An XR drive is stronger and if you have 470 HP, I would think that it would last longer. People say that due to less teeth, the 1.65 ratio is stronger than the 1.5 ratio, but I don't really know if that is the case. People also say that a 1.65 gear ratio, turning a larger prop at a lower rpm is...

    What prop for my set up?

    If you have a 1.65 drive, and turn a 22P Bravo to 5000 rpm at 10% - 12% slip the speed should be 56-57 mph. Let's assume the 500EFI has a rev limiter at 5000 rpm so it will not exceed 5000 rpm (not sure what yours has). In order to run 70 mph with a 1.65 drive ratio, at 5000 rpm and 10 - 12%...

    What prop for my set up?

    Not sure if he weight of the old Cigarette with twin 500 EFI's will help you out with much. Do you know the exact horsepower of the engine you installed in your Checkmate and the drive ratio in it now? If so, there are members with similar Checkmates that have posted their WOT speeds and with...

    What prop for my set up?

    Thanks, I would also check the accuracy of your tachometer. If your holeshot is as strong as you say, I understand you saying that you could use more pitch, but that would reduce your rpm out of desired range for that engine. Perhaps your rpm is really closer to 4800 - 5000 rpm now? If so that...

    What prop for my set up?

    First, I would think that a 415 HP 253 Convincor with a 1.5 drive ratio could turn a 24 Bravo, but maybe it would have to be labbed, but other members will answer that have a similar boat to yours. If you had a 1.65 drive ratio and turned it to 4800 rpm, you would need a 28 - 30 pitch prop...

    What prop for my set up?

    What prop do you have now? What is the rpm and GPS speed at WOT?

    3 piece Windshield for 2400 BRX or long deck

    https://www.screamandfly.com/showthread.php?360116-New-Windshields-for-Superboat-and-Rallysport Hi Coop, check out the link above. Perhaps Randy Corson can help you get a plexiglass windshield made for a lot less? You might want to call him.

    3 piece Windshield for 2400 BRX or long deck

    Can you get Caldwell Checkmate to order one for you for less? I believe it, because when I bought my boat I asked if I could have a windshield that was 6 - 8" higher. Apparently they had done that before and said it would be around $7000 extra!!! I just laughed and asked them to lower the seat...

    Checkmate in Boating magazine

    I saw that report before. I assume that is the Pulsare with the composite construction and notched transom? They claim it drives better with less chine walking. My 2020 Buycrus 24 Pulsare / 300R runs about 73 - 74 mph with a 24P Bravo FS prop. The new owner of Tom's 2020 BRX / 300R (last Bucyrus...
