    Default Blackjack24

    Killed the motor looking to replace with the same size but is discontinued trying to figure out actual options for replacemt. I do understand I will probly have to upgrade the esc one with a built-in lvc would be nice not sure what my options are

    I'm pretty sure the stock motor in that boat was a 36mm 2000kv 4 pole. I don't recall the length. You'll be able to find an aftermarket equivalent to fit. I ran the DYNM3910 stock motor from a 29 V3 blackjack in mine for a while, current version of that motor is a DYNM3831. Problem is you'll need a different motor collet, and will have to tweak the motor mount for additional clearance between the motor and the end of the stuffing tub inside the hull.

    If it were me I’d go 3000-3500 kv, on 2-3 S with a 120 amp esc. Starting with a 440/2 maybe going up to 440/3 or 442 prop depending on temps and handling.

    Honestly, keep it simple with that hull, learn what you can, but don't throw a lot of money at it. It's limited in speed due to its size, and won't take many violent crashes because it's plastic. I think the stock esc was only 30A and barely enough for the stock boat. I ran an inexpensive 120A Hobbyking in mine. The motor alone won't really increase the amp draw much, but a bigger battery or larger prop will.
