atomic 58 inch catamaran motor question

One question, that motor is not too small?

One question, that motor is not too small?

40mm by 4" it's much larger than the stock motor and can handle way more power!! These motors are consistently pushed over 4000watts.

Maybe this will help:image.jpg

Getting closer! We machines the mounting holes for the factory motor mount and drilled out the stock shaft coupler and everything seems to be going together well. Still need to do some alignment of the motor mount and tighten everything down, hope to have it in the water soon!

Looking good.

Looks like a nice fit.
But change the water lines on the motor jacket so that the water come in at the bottom nipple,
And than fills the jacket up and over flows out the top nipple to the exit line.
It should help cool the motor a lot better that way with more water around the motor can,
I try to get the exit nipple on the very top of the motor when possible

Yeah I was kind of thinking that but was also thinking it would be easier to flush the system out if the exit is on the bottom ( I run in salt water) cooling is obviously more important so I will flip it around.

Just turn the hull upside down if you need to get the last drop out,
When flushing the setup out and hull.
Also spray some WD40 in the lines and blow it though to help keep down some corrosion.

I'm preparing my ARC...

Ok so I was able to get out for a quick test run today!
So conditions were not ideal, pretty windy and some mild chop so it's hard to give a detailed comparison between my new motor and the stock but I will say its definitely an improvement in performance and the motor seems to be running pretty cool!

This motor is designed to produce some serious power and the 2500-3000 watt estimate that I am seeing is not even waking the motor up! I will bring my temp gun on the next outing but things seemed really cool!

Performance wise this is a nice step up from the stock motor, I am running same batteries, ESC and prop so it's just a straight motor swap.

At full throttle the boat would not stay in the water :) I would guess that 3/4 throttle with this motor is similar to full throttle with the stock motor. The conditions kept me from really seeing what it can do but if I was to shoot from the hip it's about 10mph faster. I have run the boat in similar conditions maybe a bit less wind and I was able to get some full throttle passes but with the new motor that was not possible. Every time I hit full throttle you could see the drive shaft and prop coming out of the water, it was very impressive

I will try to get out and run it glassy conditions and can give a better assessment but so far I'm really happy with this upgrade!

So I got another quick run in today, this time it was in good conditions. The het 1170 kv motor is a perfect fit for anyone that wants to stick with the stock ESC and 6s but looking for improved reliability and a nice step up in performance!

The motor only hits 110 degrees with the water jacket. I would guess its a good 10mph faster than stock.

With two batteries (6s 5800 in parallel) it helps keep the boat locked in pretty well and give you enough capacity for 7-8 min run times.

Next time I can get a buddy to tag along I will try to get some video.

Thank you for the info. With what prop you test with the stock one?

great news..
awesome only on 6s to push this cat so well

Yes all stock only changed the motor and the radio system...

[Bri6672]

4 more runs today and all is good! Motor is sitting at 80-90 degrees after 7 min runs. I have an eagle tree data logger and will run it next time to confirm the amps I'm pulling. Love this boat with this setup, lots of fun!
