It will fit. If you plan to use a shaft sleeve - you will need to drill bottom hole to make it bigger. And DON"T use watercooled motor and ESC - there's not too much space inside to arrange all that watertubes for cooling. BTW, if you're not so good in building boats I STRONGLY recommend to buy this kit (wooden sponson) preassembled. It was my first time and I've waste a lot of epoxy glue (and time) to build all that things.
Well, I got ADS3000 watercooled motor, 30A watercooled ESC this shaft with prop and sleeve that shown as "also buy". Had to drill hole bigger for sleeve, had some problems with motor mounting (not comfortable to screw the screws). And I used infusion kit tubes (dunno how it will be in english but it's for infusing medicals in the body) as watercool tubes. Tried to arrange watercooling inside without bends and blocks but no luck. The biggest problem with kit was glueing that two "satellites". It's curvy and need to be bended in 2 points. Afterall I don't recommend watercooling for this kit. Or at least don't use same setup XD
