You would have direct water contact with the stator but it would be a lot more water, possibly heavyer than your present plan. Would probably need some sort of baffle in the cavity too.

How are you going to get the bearing over the water pipes?

I find it difficult to believe that you're going to all this trouble, and even pressed out the axle, yet you're further weakening an already proven to be inadequate axle, and putting it back in the motor instead of replacing it with a larger stronger axle with more room for the things you want to run through it. The only other change would be going to bearings with a larger ID.

Yes, the easy way...get a bearing with the same OD and a larger ID to fit the new shaft. Xlyte bearings are crap and need replacing anyway, so just get a different size.

but i'm a bit torn in my opinion, if you are making that much heat, why just not use a bigger motor and put that energy to use.. ?
I'm running an x5305 in a 20" rim on my trike, at 72v and 60 or so battery amps, the motor and controller are barely warm after my ripping donuts and start/stop low speed full throttle runs... that's 5000w used efficiently..
X5's at over 10,000w are doing nothing but producing heat... if you want more go.. get a bigger motor.. imo..
