I disagree with you. The default esc is not cooled by water. The water pipes are on the sides of the housing. The cooling conduction towards the mid section is almost none. Putting a water cooled block directly on top of the FET's will keep them much cooler. I used thermal conductive paste in between the cooling block and the esc internals. Actually, the mod I show is sold by stumbfab commercially, and they are known for cooling mods. If you don't like the mod, it's OK, of course. Keep yours stock then. ✌️

@@CozyRC No problem Bro.But that (The water pipes are on the sides of the housing) the pipes it is a few centimeters from the center it is not big problem, it's a pure piece of aluminum (Hot , go fast to cold side) your solution is worse than the factory for only one reason! You do not have pressure to have good contact, the thermopaste it is not enough ,need screws! otherwise it would be better!✌

What is the boat size and hull type? Motor, battery voltage? I could advise you if I have some more info on your project 😀

@@CozyRC I can send you sir all details in another platform if possible. here its a bit hard to send everything. do you use facebook, discord or anything similar? thanks a lot

Send me a message on FB. My name is Cozy RC

Merci bien!

Placing the prop further from the transom, can contribute to a more stable running hull. It's easier to accurately set the prop height and angle, too.

Thank you

Thanks, Dim! It's so nice to run the boat at a fast pace, and being able to push the throttle even more 😎. I'm wondering how the RocketRC 3670 2250kV motor would work 😄

I ve run this motor in my velosmono and although the testing was short I was impressed!

​@kaprc631 I'm looking forward to your Velosmono runs.. it will be crazy fast when setup correctly, because you managed to make it very light!

The stock version uses square shaft ends, so it cannot slip? I use a collet with a 4mm flex shaft. Round end in the collet, and square in the prop shaft 👍

@@CozyRC Many thanks for your reply. I am new to this set up so probably have not got my unit adjusted correctly.

Thanks! It runs great with this 40mm 1.6 pitch gold prop. I will try the red 1.9 pitch prop, too

Yes, now it runs stable and loose, without flipping 👍 This video was with an upgraded prop already, but I will try the famous red 1.9 pitch prop as well in 40mm size 😎 I'm also considering a 2250kV motor..

@@CozyRC good choice on the kv but 1.9 you don't think it's to much?

​@@daiciuapostol79It's worth trying!

Thank you, Vinnie! I bought this boat second hand, but from a reknown Dutch RC boater, who has many fast and great running hulls. It took me just a bit of fine tuning and prop testing to let this boat rip to 67mph 😎

Bedankt Ed, dit is inderdaad een rap bootje! Ik denk eraan om de motor te upgraden. The romp loopt zo stabiel, dat ik denk dat het kan.

Thanks! It was a great meet up. Many nice boats and a friendly vibe 😎

Thanks! I love those details as well, such as the sound of the hull: drive and water slapping 😎✌️

That's why I'm impressed by it as well! The weight has to do with that, because it weighs about 3.1kg ready to run. It holds 6S 6000mAh 😅

Thanks! Yes, it has a nice and distinctive sound. Its running a 4mm flex cable, and I use a sleeve on the prop shaft to run 4.76mm ( 3/16thl props ✌️

Thanks! I'm running 1650kV on 6S. On 4S, this motor has too low rpm. For a 4S setup, look for 2200-2600kV motor 👍

Thanks! Yes, just like the real F1 Powerboats, this F1 hull turns on a dime. It's my own design and build, called the Cozy F1 T800. 👍

@@CozyRC available as a kit ARTR from you ?

I stopped selling the kit, because it was too time intensive, sorry!

That's what happens if you try to find the sweet spot for top speed 😎

@@CozyRC That it does...

You're welcome! 😎

Yes, Rc Jay with the red tunnel: youtube.com/@rc-jay?si=zZhpg7NpkxWx81uo And René with the white Red Bull tunnel: youtube.com/@reborc?si=cIMNXo7NyWDr-jut

@@jansvasta2146 Thanks! It took me a long time to fine-tune it, but it runs good now 😎

@@sakibian01 Thank you, Sakibian! Yes, many beautiful and fast boats were present!

@@CozyRC I wonder,did you guys put GPS on? Who smoked,who was the fastest?

​@sakibian01 Some guys did, but some guys don't care about the top speed number 😀. The highest speed I heard about, was 129km/h from the small cat from 05:18. I set a record with my T800 F1 Tunnel: 98km/h and also with my blue Psychocat: 108km/h 😎

@@CozyRC Congratulations,man! Setting new heights for self improvement.

Thanks! 😎

That's my Dr. Psycho Psychocat V1. It's a boat from 2001, but a very good and fast hull. I will make a separate video about it, from this event!

Through me. It will be in March, 2025 probably. It's kind of a closed event, but I will try to invite you! Otherwise, the next big event is in April, 2025, including The gas / turbine boats. That's somewhat international, including German and UK guys joining 😎

​@@CozyRC Hi. Thank you. Ok lets aim for April then. I have the Megalodon under construction, and the 1/5 tunnel. Would very much like to take a couple days and go Show off with other proud builders. Cheers

The April event is on a camp site, with small bungalows, too. So you can stay next to all the action, if you want. I keep you updated!

Zeker, ik heb ook heerlijk gevaren en het was gezellig onder elkaar 👍

Thanks! Yes, we have a lively community, with lots of cool boats! The gas boat community is big as well, but they don't allow gas boats on this lake.

@CozyRC see that's awesome!! Yep with gas boats it's the same here, tough to find a place and usually for me it's an hour drive. For electric 30 min to a fresh water lake like the one you see me always at in my videos! That's a big reason for my decisions when buying a boat!

Thank you! I think 6S 1650kV is the sweet spot for an outboard. Lots of torque, good flex shaft life, and good speed 👍

@@H2oMechanic2RC Thanks! That's nice to hear. I'm actually using some of your mods on mine, such as the carbon fiber motor mount and transom (to be applied still on mine). ✌️

@mariebaxter473 Thanks, Marie /Paul! Do you know Brenton by any chance?

@@CozyRC Dont think so, hardly get out much how these days , hope to put that right soon , and get back to running my riggers,

Thanks, Mike! I fully agree 😎

@@CozyRC Back in the 80's I had a Prather lap cat with a 3,5cc K&B outboard on it. Always welcome.

@@mikesrcgarage That's a nice hull, which some guys are still running! And the K&B legs are great, too 👍

It's my own design and build. I stopped selling the kit, due to low profit margin and a lot of work, sorry!

@@kekse1669 Thank you! The right size servo is now installed 😊

Guess what.. I bought this motor at that sale for about €16, together with 5 other motors 😅

@@CozyRC Yeah I have lots of the XK motors I bought over the years, 28 series, 36 series & 40 series. In the same sale they were selling the XK3650 for 10Euro, already had a few of these so didn't want anymore.

Yes, they are!

CCW counter clock wise prop rotation, left turning veiwed from the rear. CW clock wise, right turning veiwed from the rear.

Exactly right! I couldn't explain it better 😀 One clarification: viewed from the rear of the boat, that is.

Both will give forward thrust. Right. Which propeller is best for the counter-clockwise rotating gasoline engine.

@djihawk3496 counter clockwise rotating engine, viewed from the rear of the engine, right? In that case, you need a clockwise rotating prop, because the prop rotation is viewed from the back of the boat, as mentioned before

@CozyRC yes. Watching from the rear end of the boat. Engine rotates in CCW. But could you tell me. Other than clockwise and counter-clockwise rotation while watching from rear end. What is the effect on water for these two types of prop.

Thanks, Pete! I ran a 43mm 1.6 pitch CNC cut aluminium prop 😎

Do you think it can handle a bigger prop for 100km+?

Yes, the fastest prop I have is a 44mm 1.6pitch. The motor makes less rpm, but the speed is still higher. I might try that one, soon!
