Project Aquazepp II

RGMag · 27th September 2011, 21:20

Hi folks, my Aquazepp upgrade is nearly complete! Only waiting for the belt for the beltdrive and then the final assembly will be completed!

New 6 blade prop!

New prop shaft and internal belt drive! New gear ratio 1:3 instead of 1:5

PWM electronic´s to drive the motor in any rpm! Controlled via the old gear changing (motor adjust) knob! 12v/24v lever now acting as main switch to break circuit in case of failure!

First reed switch to start with pwm control, second reed switch to switch direct 24v volt´s to motor in case of electronics failure!

2 12V 28ah Sealed lead gel batts. Zepp running on only 24V now, just control speed via PWM!

Test drive maybe this weekend!

All the mod´s require huge work in machining the part´s, no changes to the zepp, can be rebuild to original spec´s at any time!

Good luck, looks like fun.

You know, it´s "made in germany" so no luck needed... (only joking)

I´m realy excited on how it behaves in the water, hope today the timing belt will arrive so I can finish the drive chain and see how it run´s.

The good thing is that you can change the gear on the prop shaft very easy so you can adjust the prop speed to the best results!

We´ll see how it runs, iI´ll also make a in water thrust measurement to see what it can push.

Belt drive is a nice upgrade, should run much quieter, although I've always liked the distinctive sound of a Aquazepp screaming past me in the cave!

All is done now, the zepp is running, and with the new bearings i installed today it became even more silent! The belt drive realy makes a great difference! Also it´s nice to have the possibility to adjust the gear ratio!

So, I hope I can test it during the weekend and make some measurements of speed and thrust!

At least it looks pretty cool now with the new prop

How Fast does it go?

I tried to upload a vid of the setup on youtube, feel free to check it out!

Aquazepp with belt drive and Vetus prop. - YouTube

The clicking/rattling sound comes from the broken upper bearing, those bearings were only used as spacers during the buildup, unfortunately I did not make a vid today, but I´ll sure make so UW footage of it in action, so stay tuned...

Also the belt generates noise when slowing down, this is due to the prop driving the motor instead of the motor driving the prop, in water this noise will dissappear as there the prop will slow down very fast once the control is turned down.

That is a bad ass upgrade!

Great work.
