WOW...this looks like an awesome setup for a great price! If I didn't already have a similar setup I made (took me 3 years haha) I would have a go of this.

Well done Joern!

Joern, what is the gear ratio on this set up?
Is it 1 to 1 or is it underdriven ?
If so by what % ?

It is 1,45:1
(20/29)

It is 1,45:1
(20/29)

Is that due to the nitro available in your part of the world ?
Would a 1:1 be available for use with say 40 to 50 % nitro applications?

A geared setup is a lot smoother to drive, provides better handling of the boat.
For sure, higher nitro provides more torque, no doubt, which is crucial on low rpm.
Any ratio is possible on a set up like this, it is regular module 1 gears.

And this bolts on to a standard OS lower without mods ?
What pipe is suggested to run with this setup ?

Excuse my ignorance, but I'm very interested in this setup...doesn't the engine have to spin backwards from a normal motor? Or does it require reverse rotation props...

Yes it does, this is the same setup I`ve been using for a decade.
I tried multiple pipes and found the OS T2090 and TR02 pipes to be the best option.
TR02 pipe and the header I recomend is included in this package.
Now, if you gonna throw in a lot of nitro I can not give you a decent answer as I allways ran 25%.

This is just another beauty of running geared, you can throw in any car engine on the market and it will work. (all outboard engines rotate opposite of the car engines you know) So nothing spesial required
