Custom 785 waterbox
So I am having someone build me a custom waterbox for my pro 785. I know this will not add major horsepower gains, but it is going to be cheap and I figured why not. Give me a little extra sound on the water and maybe pick up some performance on the way while shaving some weight. I was looking to see if you guys had any helpful information, thoughts or ideas, dimensions, tips, or any aftermarket waterboxes that were out there that we could maybe clone. Any sort of pictures would be great also
I know a hot seat waterbox was basically half the length of a stock one but that is all I know. Who else made an after market waterbox for the 785? Polaris race team?? Any info at all with this would be much appreciated.
Pic of the beauty. Took me many years to find one this clean but I finally found this one. All stock. Hull looks brand new.

Ya, Im actually sending mine to TDR, he said he really had no idea about a pro 785 and has never made one. Im going to send him my stock one in exchange for the one he builds me plus cash obviously. Noise in not really a concern, just dont want it to be loud and sound like crap. Just trying to send him as much information as possible so it turns out great!

No luck finding a Hotseat?

Not really. One guy on the forum had one a while ago and he wanted a ton for it. More than what it originally was worth new. I know they are rare. But not spending that much.

I have a tdr for a 1200 pro - ujustlost had it on his pro785 - a buddy of mine was thinking he might want it - I can ask if he really wants it if you are interested

i wouldn't run it on a 785.why choke down the exhaust size from 3" to 2 1/4"?i had mine made to remove the 2 1/4" size from the triple pipe setup.the tdr box had a nice krackle to it,txgp1300r said he could always hear me coming long before he could see me.i went to a stock pro785 waterbox.

Was gonna cut the 2-1/4" off open up the hole and weld on a 3" inlet

I believe the 2 1/4" goes farther back into the waterbox than just at the front bulkhead
