i run a 50 cal and like all jet skis they have their quirks. i swapped mine out to something more ready for parts as Krash is kinda its own thing and not much crosses over, so if you have an issue you could be waiting ( or buy the basic stuff that fails which seams to be electronics, and a starter), where as a SJ based motor and electronics everyone has parts and new parts are easily available and cheaper .they say the motor is an untapped diamond so there may be some good potential out of them soon. bang for your buck its a good deal on a new ski. just read the reviews and upgrades for them like a second ground seams to help some electrical issues that can arise , a toggle switch for the beige and one for the brain wouldn't hurt either. remove the primer or upgrade it. its a great starter hull and you can always upgrade it to what you want later or sell n buy something else at least it gets you out there ripping
here is the 1200 i put in mine and running the MSD total loss, bolt right in, and the switches on the left one for the beige and one for the ignition
i ran a ground wire from the battery to the starter and an extra one to the electronics and then another one from the electronics to the motor cases even though there's a ground going to the stator/ flywheel
