Chi, am I understanding correctly? Steve is going to be making ABS hulls based off of your larger yellow glass boat?

I need one of those.

Hi Gang

Not a beautiful day in the neighborhood.
The old guy that lives here just can't seem to get it in gear today, so the new kids are just sitting on the countertop getting to know each other and kind of arguing about who gets the only watercooled brushless motor we have right now. It's only a 2040 4800Kv, so I don't know if the winner of the motor battle will get the good or bad end of the straw yet. We'll see

Have fun

Is a reverse bucket available for that drive?

The standard fitment for this boat (the New Sprint 'Splash') is the 28mm drive without reverse, because the full-size sprint boats don't feature one. But the 28mm jet is available with various 'ends' including 2 types of reverse so I don't see any reason why you couldn't have one on it if you fancy it

just depends on the use you have in mind, and (of course) how deep your pockets are

It looks like you can buy and use the jet drive and replace afterwards with different "Rear" ends at a later date, or even for different days of the week or water situation including 2 kinds of reverse mechanism.
Kind of a good idea

The 2040 bit is perfectly OK (unless you are a hooligan like Chi!). Its the 4800 bit Jguilty was told about. Don't run it on any more than 2s.

You were commenting on the fact your NQD had 5 screws underneath. This came up on the thread 60 odd pages ago. For the last year or so, they've all come like that.The extra screw locates some of the stock radio gear you will be junking. Just fill the hole afterwards

Thanks Mad man on the "Screw" question, and thanks on the motor question as well. The yellow boat and 2040 4800KV are indeed his, jguilty, along with 4 2200 2S bats and spare impellors and a couple of servos. I'll still need a motor for the 2nd boat and probably wouldn't mind sticking with the 2S batteries. Something bugs me about leaky boats/ overturned boats and high voltage.

I am a few months past my need to race......... OK maybe more than 20 years beyond a need to race. Any ideas for another motor for #2 boat or is that 2040 preferred for my style and testosterone count?

Thanks for any advise.
I don't always listen good, but after 40 years of marriage, I always get both sides.

Hey Chi Daddy
Ya Jguilty must have given up. I got his stuff now. Hmmm............. what could it have been that made him less interested,
Could it have been the watercooling tube that was broken off the jacket, or was it the puffed battery that I received with the other 3 that MIGHT be OK?

We will see in the next episode of JetBoat undercovers.

So it appears. That explains why he hasn't been around for a while. Still it seems his stuff is not going to waste.

The advantages of going to 3s include using a lower Kv motor and thus getting longer run times from a given size of lipo. But if you want to stick with 2s that's perfectly fine. Just pick a motor of no more than 4200Kv next time, and perhaps lower than even that (to reduce cavitation). A 20mm, 24 or 28mm dia motor will do. Most of the original gurus seemed to go for the 20mm but if you are planning mostly lake use you could go with the bigger sizes, as long as you pick one that's not too thirsty if you are staying with 2s. People in the US will have more idea of what's available locally. Don't think you have to look for watercooled motors exclusively. You can source an aftermarket cooling jacket in aluminum or silicone for most sizes, or do as Fire has often advised and roll-your-own from alu tube. Fill it with salt before you start rolling it (to keep it from kinking), roll it around your chosen motor then take it off and use water to melt away the salt at the end of the process.

and now you've got a chance to use your JBWeld - to repair that broken cooling connection
